Best answer

Answer: 1. A, C and D only

Key idea: Check each statement.

  • A is correct: non-primate mammals show the oestrus cycle.
  • B is wrong: the first menstruation at puberty is menarche, not menopause. Menopause is the cessation of cycles at about 50 years.
  • C is correct: absence of menstruation may indicate pregnancy.
  • D is correct: cycles run from menarche to menopause.

A, C and D only is option 1.
