The correct answer is A. The Fourth Amendment
Step-by-step explanation:
In the situation described the police conducted an unreasonable search in Larry's office because the search was conducted even when the police had no clear evidence or any document that shows Larry is involved in any crime or a search is needed.
This practice is illegal according to the Fourth Amendment. Indeed, this amendment establishes searches and seizures by government or related authorities such as the police are only legal or allowed if there is a warrant, which is a document issued by a judge that shows there is a probable cause or enough evidence/reasons to make a search, especially if authorities suspect the individual has committed a crime.
