Explanations:The question asks about a river located in southern India that begins in the Deccan Plateau and flows into the Bay of Bengal. The correct answer is the Krishna River. To understand this, we need to consider the geographical context of southern India and the major river systems in the region.
The Deccan Plateau is a large plateau that covers a significant portion of central and southern India. It is bounded by the Western Ghats to the west and the Eastern Ghats to the east. The Deccan Plateau is a significant source of many rivers in India, including the Krishna River.
The Krishna River is one of the major rivers in southern India. It originates in the Western Ghats in the state of Maharashtra and flows eastward through the states of Karnataka, Telangana, and Andhra Pradesh before emptying into the Bay of Bengal. The river is approximately 1,400 kilometers long and is an important source of water for irrigation, drinking, and hydroelectric power generation in the region.
Other rivers in southern India, such as the Kaveri River, also originate in the Western Ghats and flow into the Bay of Bengal. However, the Kaveri River is located further south and does not originate in the Deccan Plateau. The Nile River and the Yellow River are not located in India and are therefore not relevant to the question.
Understanding the geographical context and the specific criteria of the question is crucial to identifying the correct river. The Krishna River meets all the specified criteria: it is located in southern India, originates in the Deccan Plateau, and flows into the Bay of Bengal. This makes it the correct answer to the question.
