Answer 1

Hint: Contraceptive devices like diaphragm, copper-T are widely used among women. Diaphragms are said to be 80- 90% effective in preventing unwanted pregnancies. Thus, these devices are one of various well-known contraceptive devices.

Complete answer:
Diaphragms are circular dome-shaped or cap-like structures made of silicone, and are placed over the cervix of females. These are commonly used by females as contraceptives. It is usually placed over the cervix so that it is properly covered and acts as a barrier for the sperms preventing them from entering the female reproductive tract. This hence prevents the fertilization of an egg with a sperm. These contraceptive devices have proved to be more effective when used along with some spermicidal cream. However, these are not considered to be as effective as compared to other contraceptive devices. Even though there are no serious health risks associated with use of diaphragms, some women might develop infections with their use. Apart from this, studies suggest that they are ineffective in protecting individuals from sexually transmitted disease.

Hence, the correct answer is option (C).

The diaphragms are placed over a part of vagina called cervix, and act as a physical barrier for the entry of sperms into the female reproductive tract to begin their journey towards the egg cell.

Note: Diaphragms act as an effective physical barrier method used by females where the sperms are prevented from entering the uterus which in term contributes to birth control. As a result, the sperms can not reach the egg cell to fertilize it. Therefore, it acts as one of the birth control methods used by the females prior before sexual contact with the male partner.
