The inability of sperm cells to move normally could prevent the production of offspring by interfering with fertilization, which is present in Option C, as fertilization is the fusion of the male and female pronuclei to form a zygote.
In sexual reproduction, fertilization is important as it is the fusion of the sperm and the ovum and forms a unique individual with a unique genetic makeup and allows for genetic diversity, which increases the rate of survival in the case of any genetic disease. Fertilization aids in adaptation because sexual reproduction results in a new, distinct type of genetic recombination that may be better suited to the changing environment.
Hence, the inability of sperm cells to move normally could prevent the production of offspring by interfering with fertilization, which is present in Option C, as fertilization is the fusion of the male and female pronuclei to form a zygote.

Halley — the traditional pronunciation of the name usually rhymes with valley — was born Nov. 8, 1656, in Haggerston, Shoreditch, London, England. His father was a prosperous soapmaker and property owner. Halley was tutored privately at home before entering St. Paul's School, where he excelled in mathematics and astronomy.
Halley entered Queen's College, Oxford, in 1673, when he was 17 years old. He brought with him a fine collection of astronomical instruments purchased by his father. While still an undergrad, he became a protégée of John Flamsteed, the Astronomer Royal. Halley made important observations at Oxford, including an occultation of Mars by the moon, and published papers on the solar system and on suns
