Many Federal and State Agencies Gather Information Through On-Site Inspections

Many federal and state agencies gather information through on-site inspections. Sometimes a search of a home, an office, or a factory is a way to get evidence to prove a regulatory violation. In connection with these inspections, and the constitutional right to freedom from illegal search and seizure,

A) administrative agencies, like the police, must generally (but not always) comply with the search and seizure provisions of the Fourth Amendment.
B) the Fourth Amendment prohibitions against illegal search and seizure do not apply to administrative agencies and they can generally search without a warrant.
C) the Fourth Amendment applies to administrative agencies, but it does not apply to civil servants and so they are free to search without a warrant.
D) agencies need a search warrant only when they intend to follow their administrative actions with a criminal prosecution.
