Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In the natural contraceptive method known as periodic abstinence, couples avoid coitus from day 10 to 17 of the menstrual cycle. Reason (R): Ovulation is expected to occur between day 10 and 17 of the menstrual cycle, making the chances of fertilization very high during this period. In the light of
Options
- ABoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).
- BBoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- CAssertion (A) is true but Reason (R) is false.
- DAssertion (A) is false but Reason (R) is true.
Correct answer
