Concept:A divergent bar graph is used to show deviations, that is, increases and decreases, from a fixed average or reference value.
Explanation:In a divergent bar graph, bars are drawn on both sides of a central baseline.
This baseline represents the given average value.
Bars extending above the baseline indicate increases from the average.
Bars extending below the baseline indicate decreases from the average.
No other type of bar graph is designed to compare values directly against an average in this way.
Therefore, the correct type of bar graph is the divergent bar graph.
Answer:C. Divergent bar graph
