Answer 1

The Correct Option is D

The correct answer is (D) : (4).

Answer 2

The correct answer is: (D) (4).

Let's analyze the phases of the menstrual cycle and match them with the correct descriptions:

• Menstruation phase: This phase involves the shedding of the uterine lining (endometrium), which results in menstrual bleeding. The correct description for this phase is "Menses."
• Follicular phase: During the follicular phase, the ovarian follicles mature, and there is a surge of luteinizing hormone (L.H.), which leads to ovulation. The correct description for this phase is "L.H. Surge."
• Luteal phase: The luteal phase is characterized by the formation of the corpus luteum, which secretes progesterone. The correct description for this phase is "Regeneration of endometrium."

Therefore, the correct option that characterizes various phases of the menstrual cycle is option (4): Menses, L.H. Surge, Regeneration of endometrium.
