Section 268 IPC defines 'public nuisance' as an act which causes:

Question

Accepted Answer

A. any common injury, danger or annoyance to the public, or to people in general dwelling or occupying property in the vicinity

1. Section 268 IPC: 'A person is guilty of a public nuisance who does any act or is guilty of an illegal omission which causes any common injury, danger or annoyance to the public or to the people in general who dwell or occupy property in the vicinity, or which must necessarily cause injury, obstruction, danger or annoyance to persons who may have occasion to use any public right.'
2. The key is COMMON injury — affecting the public, not a private individual.
3. Sections 269-294 elaborate specific public nuisances (negligent spread of disease, food adulteration, obscene acts, etc.).
4. A private nuisance is a tort, not a crime under Section 268.
5. Hence option A is correct.
