Molecular orbital theory, shapes of molecular orbitals

According to MOT (Molecular Orbital Theory), the molecular orbitals are formed by mixing of atomic orbitals through LCAO (linear combination of atomic orbitals). The correct statement(s) about molecular orbitals is/are Statement (A) : Bonding molecular orbitals are formed by addition of wave-functions of atomic orbitals of same phase Statement (B) : Anti-bonding molecular orbitals are formed by subtraction of wave-functions of atomic orbitals of same phase Statement (C) : Non-bonding molecular orbitals do not take part in bond formation because they belong to inner shells Statement (D) : Anti-bonding molecular orbitals provide stability to molecules while bonding molecular orbitals make the molecules unstable.

With the help of molecular orbital theory, draw the molecular orbital energy level diagram for N_(2) molecule. Also calculate the bond order and predict the magnetic behaviour.

Molecular Orbital Theory based trick

Molecular orbital theory as developed by Hund and Mulliken concerns with the formation of molecular orbitals formed by linear combination of atomic orbitals. The electrons are present in these molecular orbitals. The molecular orbitals are filled. The molecular orbital configuration helps us to calculate bond order which gives information about the number of bonds present between atoms. The bond order is related to bond length and bond strength. Which one of the following does not have single electron in a bonding molecular orbital?
