How is theft defined?

The definition of theft primarily focuses on the unauthorized taking or possession of someone else's property with the intent to permanently deprive the owner of that property. When considering the option that best aligns with this definition, "taking possession of someone else's belongings" accurately captures the essence of theft. It involves the act of acquiring property that does not belong to you, regardless of the method used, as long as the intent to take it without permission exists.

The other options provide scenarios that do not encapsulate the legal concept of theft. For instance, taking someone’s property by force implies robbery, which involves intimidation or violence in addition to theft. Invading someone's premises pertains more to trespassing, which is an unlawful entry but does not inherently involve the taking of property. Lastly, illegal possession of firearms is a separate legal issue that deals with weapon laws and does not relate directly to the concept of theft itself.
