Explanation:

- Infancy: This defense is available for minors. They may not be held criminally responsible due to their age.

- Self-defence: This is a valid defense. A person can protect themselves from harm using reasonable force.

- Self-preservation: This is not typically recognized as a defense in criminal law. It's about saving oneself, but not necessarily from immediate physical harm.

- Consent of the other party: This defense may apply in some cases, like in sports or with certain consensual acts, but it's limited.

Correct Answer: Self-preservation (Option 3) is not a recognized defense in the same way as infancy, self-defence, or consent.
