A-P, B-Q, C-R, D-S
A-S, B-P, C-R, D-Q
A-S, B-Q, C-R, D-P
A-S, B-P, C-Q, D-R

Solution :Linear mass density = `("mass")/("Length")= ([M])/([L])= [ML^(-1)]= [ML^(-1)T^(0)]`
`"VELOCITY gradient" = ("Velocity")/("Distance")= ([LT^(-1)])/([L])= [T^(-1)]= [M^(0)L^(0)T^(-1)]`
`"Pressure" = ("Force")/("Area")= ([MLT^(-2)])/([L^(2)])= [ML^(-1)T^(-2)]`
`"Coefficient of VISCOSITY" = ("Force")/("Area" XX "Velocity gradient")= ([MLT^(-2)])/([L^(2)][T^(-1)])= [ML^(-1)T^(-1)]`
