Answer:
C.
Explanation:
Human reproduction is any form of sexual reproduction that results in fertilisation by humans. It normally includes a man and a woman having sexual intercourse. During sexual intercourse, the contact between male and female reproductive systems leads to the woman's ovum being fertilised by the man's sperm.
In human fertilization, a hapoloid ovum is released that fuses with a haploid sperm and produces a single 2n diploid cell called the zygote.
Hence, the correct option is C.
