27.
In the complete turbulence zone (in rough pipes), the
rough and smooth pipes have the same friction factor.
laminar film covers the roughness projections.
friction factor depends upon NRe only.
friction factor is independent of the relative roughness.

Independent of Nre, but it is the function of the surface roughness.

In the complete turbulence zone, also known as the fully rough regime, the friction factor becomes independent of the Reynolds number and depends only on the relative roughness of the pipe.

I think option B is correct. Laminar flow covers the roughness projection area.
