$\begin{array}{1 1}\text{(a) The greater the difference in energy between two overlapping atomic orbitals,the more polar is the resulting bond}\\\text{(b) The bonding orbitals have more of the character of more electronegative element}\\\text{(c) The anti bonding orbitals have more of the character of mole of electropositive element}\\\text{(d) The anti bonding orbitals have more of the character of more of electronegative element}\end{array}$
