(C) Oral hormonal pills
Oral hormonal pills work by changing the hormonal balance of the body so that eggs are not released and fertilisation cannot occur.
The passage explicitly states that one category of contraceptives "acts by changing the hormonal balance of the body so that eggs are not released." This directly matches oral hormonal pills. Copper-T prevents implantation, condoms act as a mechanical barrier, and surgical blocking of fallopian tubes prevents the egg from reaching the uterus — none of these prevent egg release.
