Options

• i-a, ii - b, iii - d, iv- c

• i-b, ii - d, iii - a, iv - c

• i- c, ii - d, iii - b, iv -a

• i-d, ii - c, iii - b, iv - a

Answer 1

i-b, ii - d, iii - a, iv - c

Explanation:

• i. Menstrual phase → b. Development of primary follicle
  At the beginning of the cycle, new follicles start developing in the ovary.
• ii. Follicular phase → d. Secretion of estrogen
  Growing follicles secrete estrogen, which helps rebuild the endometrium.
• iii. Ovulatory phase → a. Rapid secretion of LH
  A surge in LH (Luteinizing Hormone) triggers ovulation.
• iv. Secretory phase → c. Secretion of inhibin
  The corpus luteum secretes hormones including inhibin, which regulates FSH.
