B. a mutation inhibiting human immunodeficiency virus from entering the host cell.

Explanation:

A mutation is a change in the genetic material of a particular organism, which can trigger a change in the organism. Mutations can be due to errors in (spontaneous) DNA replication as well as exposure to (induced) mutagen. They can also happen in somatic or germ cells. Generally, mutations go unnoticed or cause serious consequences, such as anomalies, but there are rare cases in which a mutation can benefit the body. An example of a beneficial mutation is a mutation that inhibits the human immunodeficiency virus from entering the host cell.

cell regulation is conducted by special proteins.
