B says that this could be cause by a defective seal

-A
-B
-Both
-Neither

Answer 1

A noisy water pump can be caused by a corroded bearing, but it is not the only possible cause. The correct answer is Neither, as both A and B are partially correct.

Step-by-step explanation:

The subject of this question is Science.

A noisy water pump could indeed be caused by a corroded bearing. This is because the corroded bearing can cause friction and vibration, resulting in noise. However, it is not the only possible cause. Other factors like worn-out impeller blades or cavitation can also lead to a noisy water pump.

Therefore, the correct answer to the question is Neither. Both A and B are partially correct, but they are not mutually exclusive. A corroded bearing can be one of several causes for a noisy water pump, so the answer is not solely A or B.
