A. $59 increase
B. $59 decrease
C. $691 increase
D. $691 decrease

The total amount of withdrawals was $40 x 4 = $160. The total amount of the purchase was $156. The total amount deposited was $375.

Therefore, the total change in her bank account during the week is:
-$160 (withdrawals) - $156 (purchase) + $375 (deposit) = $59 increase

Therefore, the correct answer is A. $59 increase.
