Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Turbulence causes formation of eddies and this causes energy loss.
High Reynold's Number implies high inertial forces with low viscous forces. This causes high turbulence.
