(C) The hour hand of a clock completes one full rotation $(360^{\circ})$ in $12$ hours.First,convert the time into seconds: $12 	ext{ hours} = 12 	imes 60 	ext{ minutes} = 12 	imes 60 	imes 60 	ext{ seconds} = 43200 	ext{ seconds}$.The angular speed $\omega$ is given by the formula $\omega = \frac{	heta}{t}$.Substituting the values: $\omega = \frac{360^{\circ}}{43200 	ext{ s}}$.Simplifying the fraction: $\omega = \frac{360}{43200} = \frac{36}{4320} = \frac{1}{120} 	ext{ degrees per second}$.

Angular speed of the hour hand of a clock in degrees per second is:
