What is defined as the act of taking property by violence or threat of violence?

The correct answer is the act defined as taking property by violence or threat of violence, which precisely describes robbery. Robbery is characterized by its use of force or intimidation to take someone else's property. This distinguishes it from other forms of property crime, such as theft, which does not involve violence or threats.

In the context of the other options, theft generally refers to the unlawful taking of someone else's property with the intent to permanently deprive them of it, but does not involve the use of force. Burglary involves entering a building unlawfully with the intent to commit a crime inside, typically theft, but does not specifically involve confrontation with a victim. Shoplifting is a form of theft that typically occurs in retail settings and involves stealing goods from a store without the use of force or threat.

Robbery stands out as it not only involves the act of taking someone else's property but also incorporates the element of violence or intimidation, making it a more serious crime with significant legal penalties. This definition aligns with the understanding of robbery in both legal terms and common practice, reinforcing why it is the correct answer.
