Most efficient overlapping is

The orbitals of same energy level providing the most efficient overlapping are:

Hybridisation involves the mixing of orbitals having comparable energhies of same atom. Hybridised orbitals perform efficient overlapping than overlapping by pure s, p or orbitals. Which of the following is not correctly match between given species and type of overlapping ?
