Select the incorrect statement

LH surge:
| 1. | is a dramatic sudden increase in the levels of LH during the early part of menstrual cycle and is responsible for ovulation. |
| 2. | Is a dramatic sudden decrease in the levels of LH during the early part of menstrual cycle and is responsible for ovulation. |
| 3. | is a dramatic sudden decrease in the levels of LH during the mid-menstrual cycle and is responsible for ovulation. |
| 4. | is a dramatic sudden increase in the levels of LH during the mid-menstrual cycle and is responsible for ovulation. |
Consider the following statements:
| I: | The uterine endometrium undergoes cyclical changes during the menstrual cycle. |
| II: | Estrogen secreted during the pre-ovulatory phase of the menstrual cycle helps in the development of follicle. |
| III: | hCG secreted by trophoblast cells helps in maintaining corpus luteum. |
