In formation of ethene, the bond formation between s and p- orbitals takes place in the following manner.

Options

A. `sp^(2)` hybridised orbitals form sigma bond while the unhybridised `(p_(x) or p_(y))` overlaps sidewise to form `pi `- bond.
B. `sp^(2)` hybridised orbitals form `pi`- bond while the unhybridised `(p_(z))` overlaps to form `sigma`-bond.
C. `sp^(2)` hybridised orbitals overlap with s- orbitals of H atoms while unhybridised orbitals form C - C bond.
D. `sp^(2)` hybridised orbitals form sigma bonds with H atoms while unhybridised orbitals form `pi-` bonds between C atoms.
