What may constitute a justifiable defense under the law?

A justifiable defense under the law primarily relates to situations where an individual has acted in a manner that is legally acceptable when responding to a threat or danger. Acts of self-defense exemplify this principle because they involve taking necessary and reasonable action to protect oneself from imminent harm. The law recognizes the right to defend oneself, provided that the response is proportionate to the threat faced.

In contrast, the other choices present various circumstances that do not inherently qualify as justifiable defenses under the law. Violence during protests may lead to criminal charges, as this type of conduct is often seen as unlawful rather than a justified reaction. Acts committed under duress could potentially be considered a defense, but they apply under very specific conditions wherein a person is compelled to act against their will due to an immediate threat. However, self-defense stands out as a clear and widely recognized legal justification for defensive actions.
