Population Stabilisation And Birth Control

The correct answer is option (A): (i) & (ii)
Females may inject or implant progestogen-only or a progestogen-and-estrogen combination under the skin. Progesterone will be released from these implants, which will help to postpone ovulation or avoid fertilization. They last longer than oral contraceptive tablets in terms of effectiveness. They exhibit the same efficacy as tablets. By making the cervical mucus thick and the lining of the uterus' wall thin, it hinders conception. As a result, sperm have a more difficult time reaching the egg.
