Explanation:

- Option 1: Mere use of abusive language does not establish a right to private defense. Private defense is usually justified when there is an immediate threat to life or safety, not just verbal abuse.

- Option 2: Actions taken under the right of private defense are not considered offenses as long as the conditions for exercising such a right are met, such as an imminent threat.

- Option 3: Both statements (a) and (b) are true and relevant to the laws surrounding private defense.

- Option 4: None of the above would mean that neither statement is correct, which isn’t true as both statements (a) and (b) accurately reflect legal principles regarding private defense.

Correct Answer: Option 3 - Both (a) and (b).
