A.14 hours
B.Twelve hours
C.Ten hours
D.Two hours. Wind-up clocks can't be set more than 12 hours in advance.

Answer
Two hours. Wind-up clocks can't be set more than 12 hours in advance.
Why this is the answer
A wind-up alarm clock's dial only goes up to 12 hours, so it would ring at 10 a.m. (2 hours later), not noon the next day.
