These genes are involved in the production of proteins that show a great number of variations, such as antibodies, which are used to fight infection.

Based on this information, which of the following statements is an explanation for the existence of these genes in humans?

A. These genes are needed for the upkeep and repair of mutated genes in the body.
B. There is no known function of this type of gene in the human body.
