Answer:
The correct answer is the last option.
Explanation:
In this small passage, it is clear that Ms. Slade is the maim character (she performs almost all the actions, like going for coffee and running into the friend). The son is not even mentioned in that passage, and that is why he should not be taken in consideration. The manager takes a bigger rol at the very end of the passage by asking the main character why she was late. On the other hand, the friend never says anything and the perception of time during his or her little time in the passage is determined by Ms. Slade's gasp.
