Correct Answer: B) 2, 3, 4 and 5.

Exam Relevance: UPSC, SSC, Bank PO, State PSC

Difficulty: Moderate

Explanations:

The question asks about the annual rainfall patterns in specific regions of India, namely Odisha, Jharkhand, Cachar Valley, and Manipur. To understand the correct answer, it is essential to consider the geographical and climatic conditions of each region.

Odisha, located on the eastern coast of India, receives significant rainfall due to the influence of the Bay of Bengal monsoon. The average annual rainfall in Odisha ranges from 100 to 200 cm, making it a region with moderate to high rainfall. The state's topography, with its coastal plains and hilly regions, contributes to this rainfall pattern.

Jharkhand, situated in the eastern part of India, also experiences a significant amount of rainfall due to the influence of the monsoon. The state's average annual rainfall is around 120 to 150 cm, which falls within the specified range. The presence of the Chota Nagpur Plateau and the Maikal Range influences the rainfall distribution in Jharkhand.

Cachar Valley, located in the northeastern part of India, particularly in Assam, receives moderate rainfall due to its proximity to the Bay of Bengal and the influence of the monsoon. The average annual rainfall in Cachar Valley is approximately 150 to 200 cm, which is within the specified range. The valley's geographical features, including its low-lying areas and the presence of the Barak River, contribute to this rainfall pattern.

Manipur, another northeastern state, receives significant rainfall due to its location and the influence of the monsoon. The average annual rainfall in Manipur ranges from 150 to 200 cm, which falls within the specified range. The state's topography, with its hills and valleys, influences the rainfall distribution.

The Khasi and Jaintia hills, located in Meghalaya, are known for receiving extremely high rainfall, often exceeding 200 cm annually. These regions are influenced by the monsoon and have a unique topography that contributes to their high rainfall. Therefore, they do not fall within the specified range of 100-200 cm.

Understanding the geographical and climatic conditions of each region is crucial for determining the correct answer. The regions that receive annual rainfall between 100-200 cm are Odisha, Jharkhand, Cachar Valley, and Manipur. Therefore, the correct answer is Option B: 2, 3, 4, and 5.

Option Analysis:

Option A: This option is incorrect because it includes the Khasi and Jaintia hills, which receive much higher rainfall, often exceeding 200 cm annually. Odisha and Manipur do receive rainfall within the specified range, but the inclusion of the Khasi and Jaintia hills makes this option invalid.
Option B: This option is correct. Odisha, Jharkhand, Cachar Valley, and Manipur all receive annual rainfall between 100-200 cm. These regions are influenced by the monsoon and have geographical features that contribute to this moderate rainfall range.
Option C: This option is incorrect because it includes the Khasi and Jaintia hills, which receive much higher rainfall, often exceeding 200 cm annually. While Jharkhand, Cachar Valley, and Manipur do receive rainfall within the specified range, the inclusion of the Khasi and Jaintia hills makes this option invalid.
Option D: This option is incorrect because it includes the Khasi and Jaintia hills, which receive much higher rainfall, often exceeding 200 cm annually. The other regions listed do receive rainfall within the specified range, but the inclusion of the Khasi and Jaintia hills makes this option invalid.

Mnemonic: Remember: "OJCM" for Odisha, Jharkhand, Cachar Valley, Manipur.
