Explanation:

- Option 1: 14 years of age

- Children below this age might often escape the full brunt of legal responsibility in various systems, but not under S.82 in this specific law.

- Option 2: 18 years of age

- Typically the age of majority where a person is considered legally responsible for their actions, hence not applicable here.

- Option 3: 7 years of age

- Under Section 82 of the Indian Penal Code, nothing is an offence which is done by a child under seven years of age, as they are viewed as incapable of criminal intent.

- Correct Answer

- Option 4: 10 years of age

- Though an age of concern for criminal responsibility in some legal systems, it doesn't align with S.82 under the Indian law.
