In a corridor, the element that is the target of interaction with another object is the Target.

• A. Target
• B. Destination
• C. Receiver
• D. Endpoint

Answer: (A)

When an operation involves another object acting on something, the item that is being acted upon is the target. This term explicitly identifies the object toward which the interaction is directed, which is exactly what the question describes in a corridor context. Destination focuses on where something ends up, not the object being engaged; endpoint describes a location on geometry rather than the object of interaction. Receiver implies something that merely receives something, which isn’t the standard label for the object that’s being acted upon in this context. Therefore, the term that best fits is the target.
