The elements most likely to form an ionic bond among the options given are **Na and Cl**.
Sodium (Na) is a metal and chlorine (Cl) is a non-metal. When they bond, sodium tends to lose an electron to achieve a full outer shell (forming a positively charged ion, Na⁺), while chlorine tends to gain an electron to achieve a full outer shell (forming a negatively charged ion, Cl⁻). This transfer of electrons leads to the formation of an ionic bond.
The other pairs, such as Se and Cl (both non-metals), C and O (one non-metal, one metalloid), and K and Ca (both metals), are less likely to form ionic bonds.
