(C) Given equation: $\sin ^{-1} x + \sin ^{-1}(1-x) = \cos ^{-1} x$ Since $\cos ^{-1} x = \frac{\pi}{2} - \sin ^{-1} x$, we have: $\sin ^{-1}(1-x) = \frac{\pi}{2} - \sin ^{-1} x - \sin ^{-1} x = \frac{\pi}{2} - 2 \sin ^{-1} x$ Taking $\sin$ on both sides: $1-x = \sin(\frac{\pi}{2} - 2 \sin ^{-1} x) = \cos(2 \sin ^{-1} x)$ Using the identity $\cos(2	heta) = 1 - 2\sin^2	heta$, where $	heta = \sin ^{-1} x$: $1-x = 1 - 2(\sin(\sin ^{-1} x))^2$ $1-x = 1 - 2x^2$ $2x^2 - x = 0$ $x(2x - 1) = 0$ Thus, $x = 0$ or $x = \frac{1}{2}$. Both values satisfy the domain of the inverse trigonometric functions. Therefore, $x \in \{0, \frac{1}{2}\}$.

If $\sin ^{-1} x + \sin ^{-1}(1-x) = \cos ^{-1} x$, then $x \in$
