A)Parking between 1 and 15 hours.
B)Stopping on the days indicated on the sign.
C)Parking from 9:00 on the 1st to 9:00 on the 16th.Correct
# Explanation
The regulated parking prohibition sign with numbers indicates the complete period during which parking is not permitted. In this case, the numbers "1" and "16" represent the days of the month, so the prohibition applies from 9:00 on the 1st day to 9:00 on the 16th day. This is a prolonged parking restriction, not just during certain hours of the same day.
