The appropriate domain for the problem focuses on the number of days \( t \) after Annabel returns from the market and before she bakes the banana bread. Since she bakes the banana bread 5 days after returning from the market, we are interested in the time period starting from 0 days (the day she returned with the bananas) up to and including 5 days.
Thus, the correct domain is:
\( 0 \leq t \leq 5 \)
So, the response would be:
0 ≤ t ≤ 5
