Correct option is D
The correct matching of contraception methods and their modes of action is as follows:
A. Copper-I (iv) Prevent fertilization: Copper-I IUD works by releasing copper ions into the uterus, which create an inflammatory response that is toxic to sperm, preventing fertilization. It also makes the uterine environment hostile to implantation.
B. Oral pills (iii) Prevent implantation: Oral contraceptive pills mainly prevent ovulation, but they also alter the cervical mucus and the endometrial lining, making it unsuitable for implantation if fertilization does occur.
C. Condom (ii) Sperms do not reach the cervix: Condoms act as a barrier, preventing sperm from entering the vagina and reaching the cervix, thus preventing fertilization.
D. Tubectomy (i) Egg will not reach the uterus: Tubectomy is a surgical method of female sterilization where the fallopian tubes are cut, sealed, or blocked, preventing the egg from traveling down the fallopian tube to the uterus for fertilization.
