Answer
A < B < C < D = E; The correct answer is (d)
Work Step by Step
The percent ionic character of the molecules are represented by the "y axis" in this graph.
The higher in this axis, the greater the percent ionic character.
Therefore, putting things in order of increasing height in the graph:
A < B < C < D = E;
D and E are in the same 'height", so they have the same percent ionic character.
