Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): In the computations of velocity triangles, or the torque of well-encased rotodynamic flow machines, whether of outward, or inward, flow type, the tangential component of velocity at the smaller radius flow section can be almost neglected.
Statement (II): This follows from the very concept of ‘outward’, or ‘inward’, flow — to a large extent — in visualizing the working features of the machine.

B Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I)
