We study the implications of R-parity-violating (
) Minimal Supersymmetric Standard Model (MSSM) in lepton
polarization asymmetry (ALP) in B l+l- decays. The analysis shows that the ALP
is significant only in a certain phenomenological parametric region of Yukawa coupling products and branching fraction. The analysis
further shows how 
arising from type-II Higgs Doublet
Model (2HDM) is constrained in the presence of Yukawa interactions.
