Explanation:

- The act of unlawfully entering into another’s property is called Trespass.

- Trespass means entering someone’s land or property without permission. This is a legal wrong.

- Breach of property is not a standard legal term for this act. It is not used in this context.

- Easement means the legal right to use another person's land for a particular purpose, like a right of way. It is granted with permission, not unlawfully.

- Escheat means the transfer of property to the state when a person dies without heirs.
