In q they called loss of pressure head not friction head loss. So I think answer is right.

Re is directly proportion to v.
f = 16/Re.
Hf = 4flv^2/2gd.
So, Hf is proportion to v.

Right answer because in pipe flow laminar 32u*v (average velocity) L/roh*g*d2.

Yeah, the answer is right del. p =32mu vl /r^2.

It is according to Hagen Poisennus Law.
