Explanation:

A binary ionic compound consists of exactly two different elements, with one being a metal (forming a cation) and the other a nonmetal (forming an anion).

• $\text{H}_2\text{O}$: Two nonmetals, covalent compound.
• $\text{H}_2\text{SO}_4$: Three elements, polyatomic acid.
• $\text{MgF}_2$: Metal (Mg) + nonmetal (F), two elements, ionic.
• $\text{SF}_6$: Two nonmetals, covalent compound.

Answer:

C. $\text{MgF}_2$
