In graphite,the $C$-atom is in which state of hybridisation?

Hybridisation state of $C$ in diamond is

$sp^3d^2$ hybridization is not displayed by

Oxidation of carbon with concentrated sulphuric acid gives the corresponding oxides of $C, S$ and $H$. The hybridisation of the central atoms in the oxides of $C$ and $H$ are respectively.

In $CH_4$ molecule,the hydrogen atoms around carbon are arranged as
