In circular measure, the value of the angle 11°15' is:

Answer: Option A

$$\begin{array}{rl}& 11^{\circ }15^{\prime }=11+\frac{15}{60}=11+\frac{1}{4}=\frac{{45}^{\circ }}{4}\\ & \text{We know }\pi \text{radian}=180^{\circ }\\ & 1^{\circ }=\left(\frac{\pi }{180}\right)\text{ radian,}\\ & \frac{{45}^{\circ }}{4}=\frac{\pi }{{180}^{\circ }}\times \frac{{45}^{\circ }}{4}=\frac{{\pi }^c}{16}\end{array}$$
