Correct answer: C

The hybridisation of the central atom can be calculated as

H = $${1 \over 2}\left[ \begin{matrix} \left( \begin{matrix} No.,of,electrons \ in,valence,shell \ of,atom \\end{matrix} \right) + \left( \begin{matrix} No.,of,monovalent \ atoms,around \ central,atom \\end{matrix} \right) \

  • \left( \begin{matrix} Ch{\mathop{\rm arge}\nolimits} ,on \ cation \\end{matrix} \right) + \left( \begin{matrix} Ch{\mathop{\rm arge}\nolimits} ,on \ anion \\end{matrix} \right) \\end{matrix} \right]$$

    Applying that formula we find that all the given species except [SbCl5]2- have central atom with sp3d ( corresponding to H = 5) hybridisation. In [SbCl5]2- Sb is sp3d2 hybridized.
