Explanation:
The overlapping sets which is denoted by the region B is best attributed to connote with the choice "occurs in substance that have at least one non-metal".
To form an ionic bond, a metal and a non-metal must exchange electrons in order to an electrostatic attraction to occur.
In the case of covalent bonds, non-metals shares their valence electrons to form a bond by attaining an octet configuration.
So, we see that a pre-requisite for both bonds to form is a minimum of the presence of a non-metal.
