• A. Only A
• B. Both A and B
• C. Both A and C
• D. Both B and C

Answer 1

Answer: (D)

Both B and C

Sexual receptivity is the stage when the female accepts the sperms for fertilization during the process of intercourse. The female becomes sexually receptive during the estrus phase of the menstrual cycle.

There are two phases in the animals called as the estrus and the non-estrus phase in the reproductive cycle. The estrus is the receptive phase fro the females. This is the period when the female reproductive tract is ready for accepting the sperms for fertilization.

The uterus is prepared for implantation by proliferation of the cells. This hypertrophic lining is removed and shed during the menstrual flow, if the egg does not gets fertilized.

Thus, the correct answer is option D.
