In the Application of Molecular Orbital Theory to Homonuclear Diatomic

In the application of molecular orbital theory to homonuclear diatomic molecules and ions,_____

A) the number of MOs can exceed the number of AOs used to create them.
B) AOs of dissimilar energy mix to form bonding MOs with a greater degree of stabilization.
C) an MO can hold more than two electrons because it can extend over multiple atoms.
D) inner shell electrons contribute significantly to bonding MOs.
E) better mixing of AOs leads to a greater energy difference between bonding and antibonding MOs.
