Solution

The correct option is A
Ionic compound

The compound formed is AB which is ionic in nature. As we know, an ionic compound is a chemical compound in which ions are held together by the ionic bonds. From their electronic configuration, we see that A is a metal and B is a non-metal, thereby A loses its valence electrons and forms a cation while B accepts those electrons and forms an anion. These oppositely charged ions are drawn closer due to electrostatic forces and an ionic compound is formed.
