Ionic character is directly proportional to the electronegativity difference between two atoms in a bond. The greater the difference in electronegativity, the more ionic character the bond will have.

In option C, the electronegativity difference in O-F is greater than in C-F and H-F, and the difference in Na-F is the greatest. Therefore, the order of increasing ionic character would be O-F < C-F < H-F < Na-F.
