Which of the following overlaps of atomic orbitals does not form `pi`-bond if z-axis is the internuclear axis?

Which of the following combination of orbitals do / does not form bond (if x-axis is internuclear axis) ?

According to VBT the extent of overlapping depends upon types of orbitals involved in overlapping and nature of overlapping. More will be the overlapping and the bond energy will also be high. Which of the following combination of orbitals does not form covalent bond (x-axis is inter nuclear axis) :
