Answer

Brief Explanation:

In a mutualistic relationship, both organisms benefit. Option A shows that the bacteria benefit from the plant by getting carbon and a secure environment while the plant gets nitrogen from the bacteria for protein - synthesis, indicating mutual benefit. Options B, C, and D do not describe mutual benefit.

Answer:

A. The bacteria obtain carbon from the plant and a secure environment to inhabit within the plant roots.
