Explanation: The question involves evaluating the accuracy of three statements related to historical control, wildlife distribution, and local transportation methods in India. Let's break down each statement:
1. **Sultan Ghiyasuddin Balban controlled Assam, Manipur, and Kashmir.**
- This statement is false. Sultan Ghiyasuddin Balban was a ruler of the Delhi Sultanate during the 13th century. His reign was primarily centered around Delhi and the surrounding regions. He did not control Assam, Manipur, and Kashmir, which were under different rulers or were not part of the Delhi Sultanate's direct control during his reign.
2. **Swamp deer found in Assam and the barasingha is found in Madhya Pradesh.**
- This statement is true. The swamp deer (Rucervus duvaucelii) is indeed found in Assam, particularly in the Kaziranga National Park. The barasingha (Cervus duvauceli), also known as the swamp deer, is found in Madhya Pradesh, especially in the Kanha National Park.
3. **In Assam, children go to school by crossing Bamboo & Rope Bridge.**
- This statement is true. Assam, a state in northeastern India, is known for its unique bamboo and rope bridges. These bridges are a common sight in rural areas and are often used by children to cross rivers and reach their schools.
The correct answer is (D) Only 2, 3. This option correctly identifies the true statements about the distribution of wildlife and the unique transportation methods in Assam, while excluding the false statement about Sultan Ghiyasuddin Balban's control over certain regions.
Understanding the historical context of the Delhi Sultanate and the geographical distribution of wildlife in India is crucial for answering such questions accurately. Additionally, knowledge of local customs and transportation methods in different regions of India can provide valuable insights into the cultural and geographical diversity of the country.
