  • A
    follicular phase
  • Correct answer
    B

  • C
    luteal phase
  • D
    menstruation.

Solution

The phase of menstrual cycle in humans that last for $7-8$ days is ovulatory phase. During this phase production of FSH decreases while that of LH increases which leads to ovulation on about the $14^{\text {th }}$ day. But it may range from $9^{\text {th }}$ to $16^{\text {th }}$ day (approximately).

Hence, the correct answer is option: 'B'.
