Answer:
C. Some of my friends are funny.
Step-by-step explanation:
A qualifier is a word or phrase that modifies or limits the meaning of another word, often expressing degrees or amounts. In the given responses, option C contains the qualifier "some." The word "some" limits the scope of the statement by indicating that not all of the speaker's friends are funny, but only a certain portion of them are. This word serves to qualify the extent to which the speaker's friends are funny, thus making it the response with a qualifier.
