Friction factor is always inversely proportional to the Reynolds number.

For laminar flow, the Re Number is less and hence the Friction Factor is more while for turbulent flow the Re number is more due to which the Friction factor is less.

Whether it's laminar or turbulent the friction factor is inversely proportional to Nre.

Here not clarify it, whether it is for laminar flow or for turbulence flow, so answer is D.
