In a diatomic molecule,the internuclear axis is $Z$. Which of the following bonds will be formed by the overlap of $P_x$ and $P_y$ orbitals?

In a double bond between two carbon atoms of ethene,there are

The double bond between the two carbon atoms in ethylene $(CH_2=CH_2)$ consists of:

The fluorine molecule is formed by

If the internuclear axis of a diatomic molecule is $z$,then the overlap of $p_x$ and $p_y$ orbitals results in the formation of ........

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Zero orbital overlap is an out-of-phase overlap.
Reason $R$: It results due to different orientation/direction of approach of orbitals.
In the light of the above statements,choose the correct answer from the options given below.
