Answer 1

To prevent unwanted pregnancy several methods are used, these methods are known as contraception. Contraception methods include condoms (male/ female), contraceptive implant, contraceptive injection, intrauterine device, vaginal rung, etc. Two permanent methods of contraception have occurred, named female sterilization and male sterilization.

Complete answer:

Option A: Contraceptive pills are external man-made oral pills that can prevent pregnancy 99.9% effective if taken properly. Contraceptive pills do not prevent sexually transmitted diseases. These man-made pills comprise estrogen and progesterone hormones that alter the natural hormonal cycle of a female body Which leads to the prevention of conceiving the baby. There are several contraceptive pills found, named levora, kariva, Beyaz, Natazia, etc.

Option B: The process in which pregnancy is terminated by tubal ligation through a surgical process is called the surgical method of sterilization. The tubal ligation involves 3 pathways. These are
- Tube block through bands and clips
- Tubal section remove
- Cut and fold a fallopian tube.

Option C: The couple who are unable to have a baby goes through a process called assisted reproductive technology or ART. ART involves several methods like in-vitro fertilization, cryopreservation of gametes, fertility medication usage, etc.

Option D: An intrauterine device is a T-shaped coil that is inserted into the uterus for preventing the pregnancy. This is a type of contraceptive method. This is a nonpermanent process. After removal of the intrauterine device, the female can become pregnant again. CuT, LNG-20 Cu7 is the type of intrauterine device which is used for pregnancy prevention.

Option E: Monoclonal antibodies are capable of binding with the only same antigen. It is derived from the cloning of unique White blood cells. It is used to detect diseases.

Hence, the correct answer is option (B).

Note: CuT, Cu7 is the example of a copper intrauterine device, and LNG-20 belongs to the hormonal intrauterine device. Copper intrauterine device insertion may lead to some side effects like menstrual cramp, high bleeding whereas hormonal intrauterine devices cause a reduction of bleeding.
