Answer:
Public Relations (Or more commonly known as PR)
Step-by-step explanation:
Generally, public relation is used by individuals or organizations to maintain positive image from the mass. (since a slight negative change of perceptions could resulted in a huge monetary damage for those individuals/organizations).
Example of PR in action would be when a company is handling a false accusation of using dangerous materials for their product.
In such situation, the PR team will create a campaign to make sure that the public do not get swayed with this fall information and keep their trust on the company's product. They will carefully select their words and the body language of their spokesperson to appeal to the public's concern and maintain that positive perception.
