Question

Capacitation is the biochemical process where sperm undergo changes to gain the ability to penetrate the oocyte for fertilization. Defribulation (likely a misspelling, maybe "deflagellation" but not relevant here), fertilization is the union of sperm and egg, and copulation is sexual intercourse, so capacitation matches the described process.

D. capacitation (assuming the options are labeled A to D with the last option being capacitation)
