Answer:
The correct option is: B. 33%
Step-by-step explanation:
Orbital hybridisation refers to the mixing of atomic orbitals of the atoms in order to form new hybrid orbitals. The concept of orbital hybridization is used to explain the structure of a molecule.
The sp² hybrid orbitals are formed by the hybridization of one 2s orbital and two 2p orbitals. The three sp² hybrid orbitals formed have 33% s character and 67% p character.
