Axial and Equatorial Hydrogens

Q. Carbon and silicon belong to the ${14}^{th}$ group. The maximum coordination number of carbon in commonly occurring compounds is 4, whereas that of silicon is 6. This is due to:

1. the availability of low energy d-orbitals in silicon
   
2. large size of silicon
   
3. more electropositive nature of silicon
4. both (b) & (c)
