Model Answer

(B) Condom

A condom acts as a mechanical barrier preventing sperm from reaching the egg, thus avoiding pregnancy. It also prevents direct contact between partners, thereby reducing transmission of STIs like HIV-AIDS, gonorrhoea, and syphilis.

Explanation

The passage explicitly states: "Using a covering, called a condom, for the penis during sex helps to prevent transmission of many of these infections to some extent" — making it the only option that addresses both pregnancy prevention and STI protection. Pills only alter hormones; Copper-T and surgical methods only prevent pregnancy. Examiners expect students to link both functions to the condom specifically.
