Given below are two statements:
| Assertion (A): | H - acts as both Bronsted Lowry base as well as Lewis base. |
| Reason (R): | It acts as both H ⊕ acceptor and a lone pair donor. |
| 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). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
