Probable cause protects people’s rights by making sure that

The correct answer is D. private property is searched only when reasonable.

Probable cause is a legal standard that requires law enforcement to have a reasonable belief that a crime has been committed or that evidence of a crime can be found in a specific location. This protects individuals’ rights by ensuring that searches of private property occur only when there is sufficient justification, rather than allowing arbitrary or unreasonable searches. This principle is critical in upholding the Fourth Amendment rights against unreasonable searches and seizures.
