Answer:

D

Step-by-step explanation:

What an interesting amusing question.

The formula for KE = 1/2 m v^2.

v implies that there is motion.

The answer you are looking for is the body of water that has 0 for v.

A cloud moves, so it is not the answer.

A hailstone moves until it hits the ground. I'm assuming it's either on it's way down or it is caught in some sort of updraft in a cumulonimbus cloud. So it has motion.

Same comment for a raindrop. It has a v until it hits the ground so I'm assuming it is not the answer.

I've never seen a puddle of water move. It can only evaporate. So of all your choices, this one (D) is likely the right answer.
