Which of the following is not a barrier method of birth control.
Voults
Diaphragms
Sterilzation
Cervical caps
The Correct Option is C
Solution and Explanation
The correct option is(C): Sterilization.
The option "Sterilization" is not a barrier method of birth control. Sterilization involves permanent surgical procedures such as tubal ligation in women or vasectomy in men, which prevent the sperm and egg from meeting and thus prevent pregnancy. Barrier methods, on the other hand, create a physical barrier to prevent sperm from reaching the egg. Options such as Voults, Diaphragms, and Cervical caps are examples of barrier methods of birth control.

Reproductive Health
- The biological process by which a new individual or an offspring is produced from a parent or parents that are biologically similar or identical is known as reproduction. It is the elemental trait of all known forms of life. In fact, each and every individual have life because of reproduction.
- The state or position of male and female reproductive systems during their lifetime refers to their reproductive health. The system comprises organs and glands, including the pituitary gland in our brain, which are responsible for the production and release of hormones.
- In other words, reproductive health can be described as a state of physical, mental, and social well-being in all aspects relating to the reproductive system. It includes the liberation and appropriate capacity to reproduce as and when one decides to do so, apart from having a safe and satisfying sex life.
