Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The integral \(\int \int \int (x^2+y^2+z^2)dxdydz\) taken over the volume enclosed by the sphere x2+ y2+z2 = 1 is \(\frac{4\pi}{5}\) Reason R: \(\int^{1}_{0}\int^{1}_{0}x\ dxdy=\frac{1}{2}\) In the light of the above statements, choose the most appropriate answer from the options given below:
