(C) Administration of hormonal pills
(D) Always use condoms during coitus
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (B) and (D) only
Sexually transmitted infections (STIs) spread through contact with an infected partner. The precautions are therefore about contact and about barriers.
(A) Sterilization through surgical methods — Incorrect. Sterilisation stops pregnancy by blocking the gamete passage. Sperms or secretions can still carry the infection, so it gives no protection against STIs.
(B) Avoid sex with unknown partners — Correct. This lowers the chance of meeting an infected partner.
(C) Administration of hormonal pills — Incorrect. Pills prevent ovulation and so prevent pregnancy. They do not stop germs from passing between partners.
(D) Always use condoms during coitus — Correct. A condom is a barrier that stops contact with the partner’s fluids.
