Question

The accompanying diagram shows the uterine tubes of four women ( $P, Q, R$ and $S$ ). In which two women is fertilisation impossible at present?

A

$P$ and $Q$

B

$Q$ and $R$

C

$R$ and $S$

D

$S$ and $P$

Answer

$R$ and $S$

Explanation

Solution

Figure $'R'$ is showing complete blockage of Fallopian tubes and figure $S'$ is showing tubectomy which is a surgical method of contraception in females. When both the Fallopian tubes are blocked or cut and tied, there will be no transport of gametes and thus no fertilisation.
