Solution

The correct option is A Corpus luteum
A. Corpus luteum is formed in ovary after ovulation and degenerates in absence of pregnancy but if pregnancy occurs it persists and secretes progesterone and oestrogen hormones.
B. FSH (Follicle stimulating hormone) is secreted from the anterior part of pituitary gland. It stimulates the growth of ovarian follicles in females and seminiferous tubules in males.
C. Thyroid gland is situated between the trachea and larynx in the neck and secretes thyroxine hormone which increases oxygen consumption by metabolically active tissues.
So, the correct answer is 'Corpus luteum'.
