Consider the following Assertion $(A)$ and Reason $(R)$:
Assertion $(A)$: $\int \sqrt{x-3} \left(\sin^{-1}(\log x) + \cos^{-1}(\log x)\right) dx = \frac{\pi}{3}(x-3)^{3/2} + c$
Reason $(R)$: $\sin^{-1}(f(x)) + \cos^{-1}(f(x)) = \frac{\pi}{2}$ for $|f(x)| \le 1$
Choose the correct option:

  • A
    Both $(A)$ and $(R)$ are true, $(R)$ is the correct explanation of $(A)$
  • B
    Both $(A)$ and $(R)$ are true, $(R)$ is not the correct explanation of $(A)$
  • C
    $(A)$ is true, but $(R)$ is false
  • D
    $(A)$ is false, but $(R)$ is true
