Given below are four methods (A-D) and their mode of action (1-4) in achieving contraception. Select the correct pair from the options given below:

$\begin{array}{cccc}& \text{Method}& & \text{Mode of Action}\\ \left(a\right)& \text{The pill}& \left(1\right)& \text{Prevents sperm reaching cervix}\\ \left(b\right)& \text{Condom}& \left(2\right)& \text{Prevents fertilisation}\\ \left(c\right)& \text{Vasectomy}& \left(3\right)& \text{Prevents ovulation}\\ \left(d\right)& \text{Copper-T}& \left(4\right)& \text{Semen contains no sperm}\end{array}$

• A. a = 3, b = 1, c = 4, d = 2
• B. a = 2, b = 3, c = 1, d = 4
• C. a = 4, b = 1, c = 2, d = 3
• D. a = 3, b = 4, c = 1, d = 2

Answer 1

The correct option is A

a = 3, b = 1, c = 4, d = 2

Contraceptive pills prevent ovulation. Condoms prevent the sperms from entering the female genital tract. Vasectomy is the removal of sperm duct. So, the sperm is not taken to the penis from the testes resulting in the semen devoid of sperms. Copper T is a device that prevents fertilisation of the ova by a sperm.
