• A. Probation
• B. Probable cause
• C. Professionalism
• D. Proofreading

Answer: (B)

Probable cause describes a fair probability or reasonable grounds to believe that a crime has been committed, based on the totality of the circumstances. It sits between a mere hunch and proof beyond a reasonable doubt, and it requires weighing all available factors—observations, information from witnesses or informants, corroborating evidence, timing, location, and any patterns—so that the conclusion is reasonably warranted. This standard is what legally justifies an arrest or the issuing of a search warrant, rather than relying on guesswork. For example, a combination of an observed crime in progress, a reliable identification, and corroborating video or eyewitness statements can establish probable cause to arrest or search. Other terms listed don’t match this standard: probation is a supervision or sentencing term, professionalism relates to conduct or competence, and proofreading is the process of correcting text.
