Answer 1

Hint: Human fertilisation is the union of a female gamete, the human egg, with a male gamete, the sperm, which occurs mostly in the ampulla of the uterine cylinder or fallopian tube.

Complete Step by Step Answer:
Ergothioneine, a molecule that lowers (removes oxygen from) chemical compounds, and fructose, a sugar that feeds the sperm, are both secreted by the ampulla together with a yellowish fluid.
The other exterior genital organs are enclosed and safeguarded by relatively big, fleshy folds of tissue called labia majora, which literally means "broad lips." Sweat and sebaceous glands in the labia majora create lubricating fluids. On the labia majora, hair begins to grow during adolescence.
The female organs that carry the eggs from the ovary to the uterus each month are the uterine tubes, often referred to as oviducts or fallopian tubes. The uterine tubes carry the fertilised egg to the uterus for implantation in the presence of sperm and fertilisation.
An ovum is collected from the ovaries and transferred to the uterus by the oviduct or fallopian tube.
Oocytes go through the fallopian tubes from the ovary to the uterus. The discharged oocyte is caught by cilia-waved fimbriae (finger-like structures) close to the ovary (tiny hair-like projections). Usually, the fallopian tube's ampulla region serves as the site of fertilisation.
Hence, option C is the correct answer.

Note: Preparation for implantation, maintaining pregnancy if implantation happens, and menstruation in the absence of pregnancy are the physiological activities of the uterine endometrium (uterine lining). Thus, the endometrium is crucial to the reproduction and survival of our species.
