Explanations:The southern plateau of India, also known as the Deccan Plateau, is a significant geographical region that spans across several states in the southern part of the country. This region is characterized by its distinct topography and is home to several major rivers that play a crucial role in the region's agriculture, economy, and culture.
Among the rivers mentioned in the question, the Krishna and Godavari are both major rivers that flow through the southern plateau. The Krishna river originates in the Western Ghats and flows through the states of Maharashtra, Karnataka, and Andhra Pradesh before emptying into the Bay of Bengal. Similarly, the Godavari river, often referred to as the "Dakshin Ganga" (Ganga of the South), is the second-longest river in India and flows through the states of Maharashtra, Telangana, and Andhra Pradesh before reaching the Bay of Bengal.
On the other hand, the Ganga river is located in the northern part of India and does not flow through the southern plateau. The Ganga originates in the Himalayas at the Gangotri Glacier and flows through the northern plains of India, passing through several states including Uttarakhand, Uttar Pradesh, Bihar, and West Bengal before emptying into the Bay of Bengal. The Ganga is one of the most sacred rivers in Hinduism and is a significant part of the cultural and religious landscape of northern India.
Therefore, the Ganga river is not a river of the southern plateau, making it the correct answer to the question. This question tests the geographical knowledge of the student, specifically the ability to distinguish between rivers based on their geographical location and the regions they flow through. Understanding the geographical distribution of major rivers in India is essential for various competitive examinations and general geographical knowledge.
