Which conditions suggest that a bond will be ionic?

A and C

Explanation:

Ionic bond is between a metal and a nonmetal

The rule is that when the electronegativity difference is greater than 2.0, the bond is considered ionic.

Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
