Solution

The correct option is B Mons pubis
The external genitalia of the female is generally referred to as the vulva. The vulva includes labia, vaginal opening, clitoris, external urethral opening and vestibule glands. The area between the labia minora is the vulvar vestibule. Within the vestibule are- hymen, vaginal orifice, external urethral orifice, and ducts of several glands like Bartholin’s gland, Skene’s glands, etc.
Just below the urethral opening and above the anus is the vaginal orifice. This is the opening from where the menstrual blood leaves the female body.
Mons pubis: A fleshy elevation above the labia majora. It is a cushion of fatty tissues covered by skin and pubic hair.
The clitoris is a tiny, finger-like structure lying at the upper junction of labia minora. It is an erectile organ of a female, which is highly sensitive as it contains numerous sensory nerve endings.
The external urethral orifice in females is normally present within the vestibule of the vulva. It is usually located 2-3 cm below the base of the clitoris, just above the vaginal opening. It is the point where urine exits the urethra.
