How Did the Court Distinguish a Terry Stop from a Custodial

How did the Court distinguish a Terry stop from a custodial arrest?

A) A Terry stop is conducted for a narrow investigative purpose and creates a limited intrusion on individual liberty.
B) A Terry stop is not subjected to the protections of the Fourth Amendment by its very nature, which is to delay an individual until the police can secure a warrant.
C) A Terry stop is, in essence an arrest, which the police terminate as soon as they can establish that the individual is not involved in criminal activity.
D) A Terry stop is conducted on the street and not at the police station, and the person is free to end the encounter without any police action.
