Answer:
D. The clinic opened at 7:30 A.M. and closed at 6:30 P.M.
Step-by-step explanation:
Pay attention to the times, and the amount of time the given location is open.
Only option D makes sense since the clinic open for 11 hours and the difference from the times given is exactly 11 hours; the other options are off, some give longer, and some give fewer amount of time.
