What is the difference between theft and burglary?

The correct choice highlights a fundamental aspect of theft as compared to burglary. Theft is defined as the unlawful taking of someone else's property with the intent to permanently deprive the owner of it. Importantly, theft can occur without any physical entry into a building or premises; for example, taking someone's property from their car or pocket constitutes theft without entering a defined structure.

On the other hand, burglary typically involves illegal entry into a building or structure with the intent to commit a crime inside, which may include theft but is not limited to it. It requires that there be an unlawful entry, whether it is by force or through another means. Therefore, the distinction made in the correct answer emphasizes that while theft can happen in a variety of locations without the necessity of being inside a premises, burglary specifically requires that a person unlawfully enter a space, regardless of whether theft is the ultimate goal.
