The corpus luteum is a yellow colored body which is formed after ovulation that means after the release of ovum from Graafian follicles. It is an endocrine structure which is formed in ovaries responsible for the production of a high level of progesterone and a minor amount of estradiol.

Complete step by step answer:
Option -A- LH
During the menstrual cycle, ovulation is induced by a hormone LH (Luteinising hormone). This hormone is responsible for the release of ovum in the ovaries by the rupture of Graafian follicles and therefore the formation of corpus luteum. LH is produced by the anterior pituitary gland to cause ovulation. Ovulation is caused due to LH surge. Also, this hormone is responsible for the maturation of corpus luteum.

Option -B- Estrogen
Estrogen is produced by developing follicles during the menstrual cycle. This hormone is responsible for the development of secondary sexual characters in women and the regulation of the female reproductive organs. Estrogen is produced in a great amount during the menstrual cycle by the ovaries.

Option -C- FSH
It is one of the gonadotropins which is produced by the anterior pituitary in females. This is the follicle-stimulating hormone I.e. it functions like development and maturation of different follicles during the menstrual cycle.

Option -D- LTH
The luteotropic hormone is also known as prolactin. It is a lactogenic hormone or mammotropic hormone which is produced by pituitary glands of the mammal. It mainly functions as the milk ejection hormone after parturition. They help to initiate the secretion of milk in mammals after the birth of a young one.

So, the correct answer to this question is the option"A".

Corpus luteum is known to produce a high level of progesterone which is needed to maintain the pregnancy after the fertilisation of gametes and implantation of the zygote. It is also known to produce relaxin, a hormone needed for the softening of the pubic symphysis which helps in parturition.
