Identify the sentence that best supports the following topic sentence. For a college student, sticking to a budget is difficult.

B.
Saving just five dollars a week adds up quickly.
C.
Commuter students have no choice but to pay more if gas prices go up.
D.
Students often rely on fast food for meals.
