B Correct answer

Capacitation is the final maturation step sperm undergo in the female reproductive tract, which includes the acrosome reaction. The acrosome releases enzymes to penetrate the egg's zona pellucida. It does not involve sperm size change, nuclear chromatin alteration, or mitochondrial alignment.
