Why are condoms one of the most widely used contraceptives?

All of the above.

The correct answer is Option (4) All of the above.

Condoms are popular as a contraceptive method because:

• They act as effective barriers: Condoms prevent sperm from entering the female reproductive tract, reducing the chance of fertilization and pregnancy.
• They do not interfere with the sexual experience: Condoms are designed to be used during intercourse without significantly affecting the natural flow of the act.
• They reduce the risk of STDs: Condoms provide protection against sexually transmitted diseases by preventing direct contact between sexual organs, fluids, and any pathogens they might carry.

These combined benefits make condoms a practical and widely used form of contraception.
