a.

b.

c.

d.

Explanation:

Step1: Recall the conversion formula

To convert degrees to radians, use the formula: \( \text{Radians}=\text{Degrees}\times\frac{\pi}{180}\)

Step2: Substitute the value of degrees

Given \(45^{\circ}\), substitute into the formula: \(45\times\frac{\pi}{180}\)

Step3: Simplify the expression

\(45\times\frac{\pi}{180}=\frac{45\pi}{180}=\frac{\pi}{4}\)

Answer:

D. \(\frac{\pi}{4}\)
