It looks to me as though only one of these answers clearly answers the question.

Obviously, D is wrong.

Answered by Kaled
It is? I thought it was D.
So is it A 'cuz I don't know what Accumulation means.

Answered by Kaled
Then is the answer A or B ?
Answered by Ms. Sue
Pesticide that accumulates in the bodies of predators remains in the environment.

If a pesticide is broken down by bacteria, it is rendered ineffective.
