Audiences are allowed to preview (sneak preview) actual movies such as The Hunger Games and Star Trek so that changes might be made before they are released to the general public during which stage of the new-product process

The correct answer is: market testing.

Explanation:

A market test, also known as an experimentation technique, is a research technique that consists in trying to know directly the response of people to a product, service, idea, advertising, etc., in order to obtain certain information necessary for a investigation.

Generally, a market test is carried out before the launch of a new product, in order to evaluate its acceptance or reception, and thus reduce the risk of introducing the new product to the market and that it does not have sufficient demand.

When carrying out the market test, the acceptance, reception, printing, reaction or behavior of the public before the new product is known and, based on the results, to determine if the launch of the new product is feasible, if it is necessary to make some changes before its launch, or if the launch is definitely not feasible.
