What type of crime is associated with entering a building without consent with intent to commit a felony?

The correct answer is burglary. This term specifically refers to the act of unlawfully entering a building or structure with the intent to commit a crime inside, typically a felony. The defining characteristic of burglary is the intention to commit an illegal act after gaining unauthorized entry, which aligns well with the scenario described in the question.

Burglary is differentiated from other crimes like theft, assault, and robbery. Theft involves taking someone else's property without consent but does not necessarily involve unlawful entry into a building. Assault refers to causing harm or the threat of harm to another person, typically without regard to property crimes. Robbery, on the other hand, involves taking property from a person through force or intimidation, rather than simply breaking and entering with intent to commit a crime inside. Thus, burglary is the most accurate term for the described scenario.
