Correct Answer: Option A
Explanation

When s and p block elements react, the bond formed is typically ionic or electrovalent, as s-block elements tend to lose electrons to achieve a stable electron configuration, while p-block elements, especially nonmetals, readily gain electrons. These elements(alkali and alkaline earth metals) have low electronegativity and readily lose electrons to form positively charged ions (cations). 

On the other hand,the P-block elements, especially non-metals like halogens and oxygen, have high electronegativity and readily gain electrons to form negatively charged ions (anions). The electrostatic attraction between these oppositely charged ions results in the formation of an ionic bond or electrovalent bond.
