The correct options are
A Methane
B Ethane
sp3 hybridisation is observed when one s and three p orbitals of the same atom intermix to form four hybrid orbitals. The newly formed orbitlas are called sp3 hybridised orbitals having identical shape and energy.
The given table shows the molecular formula and hybridisation of carbon atom present in the compound.
