No the Correct Answer is B.  The explaination is  as follow;
When the wave functions of same phase are added, bonding molecular orbitals are obtained. 
When wave functions of same phase are subtracted, anti bonding molecular orbitals are obtained. 
The non-bonding molecular orbitals do not take part in bond formation because they belong to inner shells and they do not overlap significantly. 
The bonding molecular orbitals provide stability to molecules while anti bonding molecular orbitals make the molecules unstable.

Explanation:

According to Molecular Orbital Theory (MOT), molecular orbitals are formed by the linear combination of atomic orbitals (LCAO). In this process, atomic orbitals overlap and combine to form molecular orbitals, which are delocalized over the entire molecule.

Statement (A): Bonding molecular orbitals are formed by the addition of wave-functions of atomic orbitals of the same phase. This means that when atomic orbitals of the same phase interact and combine, they form a bonding molecular orbital. The addition of wave-functions results in constructive interference, leading to a stable bonding orbital.

Statement (B): Anti-bonding molecular orbitals are formed by the subtraction of wave-functions of atomic orbitals of the same phase. In this case, when atomic orbitals of the same phase interact and subtract, they form an anti-bonding molecular orbital. The subtraction of wave-functions results in destructive interference, leading to an unstable anti-bonding orbital.

Statement (C): Non-bonding molecular orbitals do not take part in bond formation because they belong to inner shells. Non-bonding orbitals are formed when atomic orbitals do not overlap significantly with other atomic orbitals. These orbitals are localized on specific atoms and do not contribute to bond formation. They are generally filled with electrons from the inner shells or lone pairs of electrons.

Statement (D): Anti-bonding molecular orbitals provide stability to molecules, while bonding molecular orbitals make the molecules unstable. This statement is incorrect. Bonding molecular orbitals provide stability to molecules by lowering the overall energy of the molecule. On the other hand, anti-bonding molecular orbitals have higher energy than the atomic orbitals and can potentially destabilize the molecule. However, it is important to note that the stability or instability of a molecule depends on the overall bonding and anti-bonding interactions and not solely on the presence of bonding or anti-bonding molecular orbitals.

Therefore, the correct statements about molecular orbitals are:

Statement (A): Bonding molecular orbitals are formed by the addition of wave-functions of atomic orbitals of the same phase.

Statement (B): Anti-bonding molecular orbitals are formed by the subtraction of wave-functions of atomic orbitals of the same phase.

Statement (C): Non-bonding molecular orbitals do not take part in bond formation because they belong to inner shells.
