The size of the d orbitals in Si, P, S and Cl follows the order.
(a) $\mathrm{Cl}>\mathrm{S}>\mathrm{P}>\mathrm{Si}$
(b) $\mathrm{Cl}>\mathrm{P}>\mathrm{S}>\mathrm{Si}$
(c) P $>$ S $>$ Si $>$ Cl
(d) Si $>$ P $>$ S $>$ Cl
Answer Explanation Size of d-orbitals decrease with decrease in size of element. The decreasing order of size is Si > P > S > Cl. Therefore decreasing order of size of d-orbitals is Si > P > S > Cl.
