The hormone produced by the labelled structure X is
Correct answer: B. Progesterone
- A. Estrogen
- B. Progesterone
- C. Pituitary gland
- D. Luteinising hormone
Explanation
The structure labelled X is the corpus luteum, which is responsible for producing progesterone. Progesterone levels rise after ovulation, thickening the uterine lining to prepare for a potential pregnancy. Estrogen and progesterone are produced by the ovaries, not by the pituitary gland. The option 'pituitary gland' refers to the structure itself, not a hormone.
