Question

q: if you talk to your mother for a brief time, you might say:
a. only \hello\
b. everything that happened to you during the past three days
c. enough to last for fifteen minutes
d. im not sure

Explanation:

The question is about appropriate communication duration when talking to one's mother briefly. Option a is too short for a "brief talk" (just saying hello is very minimal), option b is too long (sharing everything from three days would be extensive, not brief), and option d is not a descriptive answer about the talk's content/duration. Option c, "Enough to last for fifteen minutes", fits the idea of a brief but not extremely short conversation.

Answer:

c. Enough to last for fifteen minutes
