List-I (Term)		List-II (Expression)
A.	Discharge, Q	1.	\[\frac{16\mu }{\rho \,VD}\]
B.	Pressure drop, \[\frac{\Delta P}{L}\]	2.	\[\frac{\pi \,{{d}^{3}}\Delta p}{128\,\mu L}\]
C.	Friction factor, \[f\]	3.	\[\frac{32\,\mu \,V}{{{D}^{2}}}\]
		4.	\[\frac{\pi {{d}^{4}}\Delta p}{128\,\mu L}\]

Codes:

A) A\[\to \]2, B\[\to \]3, C\[\to \]4

B) A\[\to \]4, B\[\to \]3, C\[\to \]1
