Solution
The correct option is Cpx+s
A non-bonding molecular orbital (NBMO) is a molecular orbital whose occupation by electrons neither increases nor decreases the bond order between the involved atoms. With pz being an internuclear axis, if an s orbital approaches a p orbital from a different angle (not z-axis) both constructive and destructive interference occurs. So, the gain is the same amount as loss and as a result, no bond can be formed.
