Given below are two statements:
| Assertion (A): | [NiCl4]2− is paramagnetic while [Ni(CO)4] is diamagnetic though both are tetrahedral. |
| Reason (R): | CO is a strong field ligand, thus pairing of electrons takes place in [Ni(CO)4]. |
| 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. | (A) is False but (R) is True. |
