• C. Both A and R are correct and R is the correct explanation for A.
• D. Both A and R are correct but R is not the correct explanation for A.

Answer 1

The correct option is A Only A is correct.

Millions of sperms are produced by the testes. These sperms enter the female reproductive tract. Most of them perish before reaching the egg. Remaining sperms come in contact with the egg and only one of them may fuse with the ovum. This leads to fertilisation and hence the zygote is formed.
