Hint: A gland is an organ which produces and releases certain substances that perform a specific function in the body. The different types of glands found in the human body are- Sweat gland, sebaceous gland, parathyroid gland, pineal gland, thyroid gland etc.

Complete answer:
A temporary endocrine gland in humans is the corpus Luteum. Glands are the organs that release certain substances in the body of an organism and they perform specific functions in the human body. There are two types of glands namely Exocrine glands and endocrine glands.
a) Exocrine gland: These are also called glands with duets. The secretion of these glands enter into the duct and end up on the epithelial surface. Ex- Sweat glands, salivary gland etc.
b) Endocrine gland: They are ductless glands. The secretion of this gland does not enter into the duct and so is called ductless gland. They release sections directly into the bloodstream. Ex- Pineal gland, pancreas Corpus luteum is the gland found in the body of a female. It is a temporary gland because it secretes progesterone which is essential for maintaining early pregnancy. It develops after evaluation from ruptured follicle during luteal phase.

Therefore, from the above explanation the correct option is (C) Corpus luteum.

Note: The function of corpus luteum is as follows,
i) It forms cells of the ovarian follicle during the ovulation.
ii) It plays an integral role in the regulation of early pregnancy and menstrual cycle.
iii) It secretes progesterone and estrogens.
iv) In case the egg is not fertilized, the corpus luteum becomes inactive after 10 to 14 days and then menstruation occurs.
