What is burglary defined as?

Burglary is defined as the unlawful entry into a structure with the intent to commit a crime, typically a felony. The correct choice captures the traditional understanding of burglary, which often emphasizes the element of entering a dwelling with the purpose of committing a felony. This definition is rooted in common legal frameworks where the seriousness of the crime is underscored by the intrusion into someone's home, highlighting both the act of entering without permission and the intent to engage in a criminal act.

While other options mention different types of entering or stealing, they do not encompass the full legal definition of burglary. For instance, breaking into a vehicle and stealing from a store may imply theft but do not involve trespassing into a dwelling or structure with the intent to commit a felony. Similarly, entering an office space could suggest unauthorized entry but lacks the specification of intent to commit a serious crime, which is vital in the legal definition of burglary. Thus, the correct answer embodies both the nature of the entry and the intent behind it, aligning with established legal principles.
