Answer 1

Answer: (A), (B), (D)

The correct options are
A Prevents implantation
B Prevents entry of sperms
D Prevents ovulation

Pills inhibit ovulation and implantation by inhibiting the secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH). They also alter the cervical mucus such that sperms are retarded and hence are prevented from entering the cervix.
