D. Persuade listeners to embrace democratic freedoms.

Explanation:

President Ronald Reagan gave his Address at Moscow State University on May 31, 1988, during his visit to the Soviet Union. And during his meeting with the students of the University, he stressed on the importance of democracy and one's freedom and rights.

Standing under the bust of Vladimir Lenin, Reagan addressed the students, stating that he wants to talk "about a very different revolution" [. . .] quietly sweeping the globe without bloodshed or conflict". He also proclaimed that "Democracy is the standard by which governments are measured", thus playing with the minds of the students about the need for a democratic government and approach. Talking about how freedom is an open belief in America, he stressed on how Americans practice it, be it politically or religiously.

Thus, the one purpose of this speech is to try to persuade the students, the listeners about the need to embrace democratic freedoms.
