### Differential Equation Solution Selection

#### Problem Statement:

Find a particular solution of the differential equation \( y'' + y = \sin x + x \cos x \).

Select one of the following options:

a. \( \frac{1}{4} (x^2 \sin x - 2 x \cos x) \)

b. \( \frac{1}{4} (x^2 \sin x - x \cos x) \)

c. \( \frac{1}{2} (x^2 \sin x + x \cos x) \)

d. \( \frac{1}{2} (x^2 \sin x - 2 x \cos x) \)

e. \( \frac{1}{3} (2 x^2 \sin x - x \cos x) \)

#### Answer Options:

- ○ a
- ○ b
- ○ c
- ○ d
- ○ e

#### Instructions:

Carefully consider each potential solution and select the one that correctly satisfies the differential equation \( y'' + y = \sin x + x \cos x \).
