What is permitted any time an officer fears for their safety?

The option regarding a pat down is the correct response because it relates directly to the officer's ability to ensure their safety during a stop. When an officer has a reasonable belief that their safety is at risk, they are permitted to conduct a pat down of the individual for weapons. This procedure, often referred to as a "Terry stop," is grounded in the legal precedent established by the Supreme Court case Terry v. Ohio, which allows officers to perform a limited search for weapons if they suspect a person may be armed and dangerous.

A search warrant requires probable cause and typically involves a more extensive search of a location rather than an individual, and it can't be conducted simply based on an officer's fears for their safety. Interrogation pertains to questioning a suspect and does not inherently relate to safeguarding an officer's personal safety. Issuing a citation involves documentation of an offense but does not address immediate safety concerns. Thus, the pat down is specifically designed as a protective measure during situations where safety could be compromised.
