D. temperature

Answer 1

I would say B ._. tho I'm not good at math

Answer 2

Option B is the right answer

Explanation:

Given that on a beach, there is a positive correlation between the number of bottles of water a person drank and the number of whales they spotted.

The height of person has nothing to do with no of whales and so the age also.

Temperature is irrelevant here.

Only option B time spent on the beach is the lurking variable since the more the time spent on beach the more are chances of watching a whale.

Hence Option B is the right answer.
