Suppose an agency inspector, such as an OSHA safety inspector, discovers an apparent violation of a regulation at a business being inspected:

the U$.$S$.$ Attomey for the relevant district must be contacted to begin prosecution

under the Administrative Procedures Act, a complaint must be filed and a notice of violation sent to the company

the inspector must file a formal complaint, but the company could agree to correct the problem before litigation

all suspected violations must be reported to a U$.$S$.$ Attomey for consideration for prosecution

none of the other choices
