Which is not an example of effective nonverbal communication?

a. a businessman wearing a suit to his corporate meeting

b. applause during the end of a musical performance

c. cheering your favorite team during a big game

d. a public speaker delivering a congratulatory speech

Based on given choices, I would say that D is not an example of effective nonverbal communication, because it is verbal (speech). Option A is definitely a positive example of nonverbal communication. Choices B and C are related to the same - positive reaction to a performance, which means both are a successful example of nonverbal communication - no words of comment were used (applause and cheering as a set of reactions and ways to express any reaction, not a communicate expressed in words).
