A police officer notices the presence of a stolen car in Margaret's driveway, seizes the car, and arrests her. Margaret expected that her driveway was a private space. The Fourth Amendment's protection against searches and seizures would:

Apply, because Margaret has a reasonable expectation of privacy.

Not apply, because the Fourth Amendment does not apply to private citizens.

Not apply, because Margaret's expectation of privacy is not one that society would consider reasonable.

Apply, because Margaret actually expects privacy.
