The correct answer is c) Framing.
When marketing companies focus information on success rates, they are utilizing the concept of framing. Framing, as a theory of mass communication, refers to how the media packages and presents information to the public. By selectively framing the stories and events they report on, marketing companies can encourage certain interpretations and influence how people view reality.

This framing technique appeals to people's desire for positive information and increases their receptivity to the message.
