Question

How do carbon and silicon differ with regard to the types of orbital available for hybridization?​

Answer 1

Thus Si has 3d orbitals in addition to 3s and 3p orbitals available for bonding in its outer level, to form up to 6 hybrid orbitals, whereas carbon atom has only 2s and 2p orbitals available in its outer level to form 4 hybrid orbitals.
