Explanations:The question asks which match is not correct among the given options. To answer this, we need to understand the geographical locations of the dams and rivers mentioned in the options. Each option pairs a dam or river with a state in India. The correct answer is the one where the dam or river is incorrectly associated with the state.
Let's examine each option in detail:
Option A: Hirakud Dam is located in the state of Orissa (now Odisha). The Hirakud Dam is one of the longest dams in the world and is built across the Mahanadi River. This option is correct as the Hirakud Dam is indeed located in Orissa.
Option B: The Mahanadi River flows through the state of Chattisgarh. The Mahanadi is one of the major rivers in central India and is an important source of water for the region. This option is correct as the Mahanadi River is indeed located in Chattisgarh.
Option C: The Mettur Dam, also known as the Stanley Reservoir, is located in Tamil Nadu. It is built across the Kaveri River and is a significant source of irrigation and hydroelectric power. This option is correct as the Mettur Dam is indeed located in Tamil Nadu.
Option D: The Almatti Dam is located in the state of Karnataka, not Kerala. It is built across the Krishna River and is a major source of hydroelectric power for the region. This option is incorrect as the Almatti Dam is not located in Kerala but in Karnataka.
Therefore, the correct answer is Option D: Almatt-Kerala, as the Almatti Dam is incorrectly associated with Kerala. The Almatti Dam is actually located in Karnataka.
