Answer
C
Work Step by Step
We solve the equation using the properties of trigonometric functions. Note, there is a general solution since trigonometric identities go up and down and this can pass through a given value of y many times. Solving this, we find:
$$\sin \left(x\right)=\frac{1}{2} \\ x=\frac{\pi }{6}+2\pi n,\:x=\frac{5\pi }{6}+2\pi n$$
