Answer & explanation
Correct answer: option 2
The correct answer is option 2: Both Assertion (A) and reasoning (R) are correct, but R is not the correct explanation of A.
Assertion: All the lift canals of the Indira Gandhi Canal system originate at the left bank of the main canal. This is correct.
Reasoning: In the lift canal, the water is lifted up to make it flow against the slope of the land. this is also correct.
However R does not explain A. However, the Reason does not explain why all the lift canals originate specifically from the left bank of the main canal. The Reason only explains the concept of lift canals in general, not the specific geographical arrangement of the Indira Gandhi Canal system. Therefore, both statements are correct, but R is not the correct explanation of A.
