Solution

The correct option is B


For this let's look at the valence electrons i.e. electrons in outer-most orbit of A and B, which are given respectively as 3 and 6.

The element A prefers to donate 3 electrons to attain stability rather than gaining 5 electrons. Similarly element B prefers to gain 2 electrons to attain octet configuration rather than losing electrons.

Hence the valencies of A and B respectively are 3 and 2.

The chemical formula of the compound would be A2B3 as 2 A atoms can donate 6 electrons to 3 B atoms, thereby satisfying both the elements.
