I'm not quite sure what you mean, but the answer to "Which of the following best describes a Target-Action method: ?" would be "Sending a specific message to a designated object or class"

The stored information consists of two items of data: an action selector, which identifies the method to be invoked, and a target, which is the object to receive the message. The message sent when the event occurs is called an action message. Although the target can be any object, even a framework object, it is typically a custom controller that handles the action message in an application-specific way.
