| 2. | A large haploid secondary oocyte and a small haploid first polar body |
| 3. | A large diploid secondary oocyte and a small haploid second polar body |

| I: | The presence or absence of hymen is not a reliable indicator of virginity or sexual experience. |
| II: | It is a membrane that often covers the opening of vagina partially. |
| I: | During pregnancy, there is no menstruation. |

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. Only I is correct.
4. Both I and II are incorrect.
