Under Section 31 of the Bharatiya Nyaya Sanhita, when is a communication NOT an offence?

The correct answer is Option 1.

Key Points Section 31. Communication made in good faith
No communication made in good faith is an offence by reason of any harm to the person to whom it is made, if it is made for the benefit of that person.
Illustration
A, a surgeon, in good faith, communicates to a patient his opinion that he cannot live. The patient dies in consequence of the shock. A has committed no offence, though he knew it to be likely that the communication might cause the patient’s death.
