To administer 100 mg of furosemide over 4 hours, the rate should be 100/4 = 25 mg/hour.

Each 500 mL bag contains 200 mg of furosemide. To administer 100 mg of furosemide, we need 100/200 = 0.5 of the bag.

To administer 0.5 of the 500 mL bag over 4 hours, we need a flow rate of 500 mL x 0.5 / 4 hours = 63 mL/hour.

Therefore, the correct answer is C.
