Correct option is A
The correct answer is: A – A chain pump is suitable to lift water to heights up to 12 m from the water surface in the well, canal or stream.
Explanation:
The statement in A is false because a chain pump is typically used for lifting water to heights of up to 6 meters, not 12 meters. It consists of a series of buckets attached to a chain that lifts water from a well, canal, or stream, but it becomes less efficient beyond certain heights, usually around 6 meters. Therefore, the claim of lifting water up to 12 meters is incorrect.

Key Points:
Chain pumps are designed to lift water to a maximum of around 6 meters.
They become less effective when lifting water to greater heights, beyond their optimal capacity.
