The correct answer is a. (1) The green screen; (2) a fake background.

Explanation:

A green screen is a technique used to create special effects layering two different images or videos. Using this way, it is possible to manipulate the background in many different ways. Green screen is very useful when the background is not available because of historic context, or science fiction, or something that is very expensive for the production. Since it is not real, it could be said that a fake background is created through this.
