Verified by Experts

The correct Answer is:
C
Figure 'R' is showing complete blockage of Fallopian tubes and figure 'S' is showing tubecomy which is a surgical method of contraception in female. When both the Fallopian tubes are blocked or cut and tied, there will be no transport of gametes and thus no fertilisation.
