Hybridization is the chemists attempt to explain the observed molecular shape by constructing hybridized atomic orbitals with the appropriate inter orbital angles. The molecule for which deviation from normal bond angle is observed, VSEPR theory suggests electron pair repulsive interaction \( (l p-l pl p-b pb p-b p) \). While from hybridization point of view that is departure from normal hybridization because the angle between any equivalent hybrid orbitals determine the fraction of \( s \) and \( p \) characters of the hybrid and vice-versa.

An element ' \( A \) ' has outer shell configuration of \( 5 s^{2} 5 p^{6} \). If \( A \) forms covalent compound \( A \mathrm{~F}_{2} \) with fluorine. The orbitals used by ' \( A \) ' for bonding are:
(a) \( d \)-orbitals
(b) \( p \)-orbitals
(c) \( s p \)-hybridized orbital
(d) \( s p^{3} d \) hybrid orbital
