A) \[128.5{}^\circ \]

B) \[142.5{}^\circ \]

C) \[127.5{}^\circ \]

D) \[141.5{}^\circ \]

Correct Answer: C

[c] Angle tracked by hour hand in 12 h = \[360{}^\circ \]

Angle tracked by hour hand in 4 h 15 min \[=\frac{17}{4}h\]

\[={{\left( \frac{360}{12}\times \frac{17}{4} \right)}^{{}^\circ }}=127.5{}^\circ \]
