Answer 1

The Correct Option is D

Periodic abstinence is a natural method in which the couples avoid or abstain from coitus from day $10$ to $17$ of the menstrual cycle when ovulation could be expected. The effectiveness of this method is limited because only a few women have regular menstrual cycle and thus the actual time of ovulation cannot be predicted as the ovulation in humans occurs about $14$ days before the onset of the next menstruation.
