1. Statement I is correct but Statement II is false
2. Statement I is incorrect but Statement II is true
3. Both Statement I and Statement II are true
4. Both Statement I and Statement II are false
| I: | The primary follicles get surrounded by more layers of granulosa cells, a theca and shows fluid filled cavity antrum. Now it is called secondary follicle. |
| II: | Graafian follicle ruptures to release the secondary oocyte from the ovary by the process called ovulation. |
1. Statement I is correct but Statement II is false
2. Statement I is incorrect but Statement II is true

| 1. | B - Corpus luteum - secretes progesterone |
| 2. | A - Tertiary follicle - forms Graafian follicle |
| 3. | B - Corpus luteum - secretes LH |
