Detailed Solution

A and R are true, but R explains A.

Assertion (A): Not all copulations lead to fertilisation and pregnancy. Fertilisation is the process of the sperm meeting and merging with the egg (ovum), does not always occur during sexual intercourse. There are various factors and conditions that can prevent fertilisation, such as the timing of intercourse relative to the woman's menstrual cycle, the use of contraceptives, the presence of fertility issues, and more.

Reason (R): Fertilisation can only occur if the ovum and sperms are transported simultaneously to the ampullary region. The ovum is released only once in a monthly cycle by the female and it is active (receptive of sperm) only for 24 hours.
