Answer 1

The correct option is C I and II

Oral administration of the small doses of either progestogens or progestogen oestrogen combinations is one of the contraceptive method used by the females. They are used in the form of tablets and hence, are popularly called the pills. They inhibit ovulation and implantation as well as alter the quality of cervical mucous to prevent or retard entry of sperms. Pills are very effective with lesser side effects and are well accepted by the females.
Contraceptive pills do not inhibit spermatogenesis nor they prevent the ejaculated semen from entering the female vagina.
