3. II, III and IV
4. I, II, III and IV
| Assertion(A): | Gymnosperms are called naked-seeded plants. |
| Reason(R): | The seeds remain exposed after their fertilization. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true, but (R) is not the correct explanation of (A). |
