The stacked bar chart below shows the market share percentages for three companies (X, Y, Z) in two consecutive years. Which company experienced the greatest absolute percentage point change in market share between Year 1 and Year 2? (Assume Year 1: X=40%, Y=35%, Z=25%; Year 2: X=35%, Y=45%, Z=20%)
✓ Correct Answer: Option B
Company X change: |35% - 40%| = 5 percentage points. Company Y change: |45% - 35%| = 10 percentage points. Company Z change: |20% - 25%| = 5 percentage points. Company Y had the greatest absolute change.
