| Read the assertion and reason carefully to mark the correct option out of the options given below: |
| Assertion: Activating groups are electron donors. |
| Reason: Nitroso group is activating group. |

B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
