Explanation:

Action: The term action is described as "built-in button shapes" that can be useful in adding a specific presentation and is set to link on any other slide, perform the same action, and play a sound, etc.

StandardController: In computer science, the term "StandardController" is described as an object that is being provided automatically for any of the standard and every custom objects, and is bindable to a specific "Visualforce page component" associated with the "StandardController" phenomenon. However, it is responsible for providing a specific reference to a particular list of record directed to a common action set for default navigation as well as data processing.

Extension: The term extension is described as an "identifier" that is being specified as one of the suffixes associated with the name of any of the computer file. It is responsible for determining the characteristics of the contents of a specific file and its uses.
