Solution
The correct option is D Swimming Sperms move actively in the female genital tract by swimming. The presence of the tail in the sperm help it to swim through the uterus. The aspiratory action of the uterus and the peristaltic movement of the fallopian tube help in the movement of sperm. Cervical mucus is said to assist the sperms in swimming up the female genital tract.
