Correct answer
CA-III, B-II, C-IV, D-I

Step-by-step explanation

(A) Pressure gradient is stated as dPdx=FAl=MLT-2L2L=M1L-2T-2   (III)

(B) Energy density is stated as u=EnergyVolume=ML2T-2L3=M1L-1T-2   (II)

(C) Electric field is stated as E=ForceCharge=MLT-2AT=M1L1T-3A-1   (IV)

(D) Latent heat is stated as L=HeatMass=Energy Mass=ML2T-2M=M0L2T-2     (I)
