  1. A.Pineal gland
  2. B.Corpus cardiacum
  3. C.Corpus luteum✓
  4. D.Corpus allatum

Correct Answer

(C) Corpus luteum

Solution & Explanation

Answer: (c) Corpus luteum Solution: After ovulation, the ruptured ovarian follicle is converted into the corpus luteum, which secretes mainly progesterone. It functions as an endocrine structure only temporarily (during part of the menstrual cycle/pregnancy) and then degenerates, making it a temporary endocrine gland. The pineal gland is permanent, while corpora cardiaca and allata are insect (not human) structures. NCERT Reference: Chapter 19, Page 246, Line(s) 38-40 — "After ovulation, the ruptured follicle is converted to a structure called corpus luteum, which secretes mainly progesterone."
