Detailed Solution

The correct answer is (b) menstruation.

Menstruation is the monthly process in human females where the inner lining of the uterus (endometrium) breaks down and is shed through the vagina if fertilization does not take place. This is commonly known as the menstrual period.

Duration: Menstrual bleeding usually lasts 3–7 days.
Cycle Length: The complete menstrual cycle typically spans 28 days (but can range from 21 to 35 days).
Biological Purpose: The uterus prepares every month to receive a fertilized egg. When fertilization does not happen, the thickened lining is no longer needed and is removed from the body as menstrual blood.

This process is a crucial part of the reproductive cycle in humans and marks the start of a new cycle.
