Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:
Assertion (A): The uterine endometrium of woman regenerates after menstruation.
Reason (R): Hormones secreted by the growing follicles during follicular phase induce uterine endometrium proliferation.
In the light of the above statements, choose the most appropriate answer from the options given below.

Oestrogens secreted by the growing follicles cause regeneration of endometrium.

Assertion (A) is correct. The uterine endometrium of a woman regenerates after menstruation.

Reason (R) is correct. Hormones secreted by the growing follicles during the follicular phase induce uterine endometrium proliferation.

This reason explains why the uterine endometrium regenerates. It attributes the regeneration to hormones secreted by growing follicles during the follicular phase of the menstrual cycle. The follicular phase is characterised by the development of ovarian follicles, and these follicles release hormones such as oestrogen. Oestrogen, in turn, stimulates the proliferation (growth) of the uterine endometrium.

Both A and R are true, and R is the correct explanation for A.
