The correct answer is A .

The CPCM course emphasizes turning data into insights and then into action. It states that category managers must draw insights from data, understand tactical analysis, and identify category opportunities that can be acted on through category tactics. This question is testing exactly that: not just calculating the gap, but identifying the gap, the source of the gap, and the dollar opportunity.

From the chart:

Mid-Mart ACV share = 25.0%

Mid-Mart Snack share = 20.0%

So Mid-Mart is:

25.0% - 20.0% = 5.0 points behind Total Store

The total Snack market is $200,000 . If Mid-Mart achieved its fair share of Snacks based on its 25% Total Store ACV share, expected Snack sales would be:

$200,000 × 25% = $50,000

Actual Mid-Mart Snack sales are:

$40,000

So the opportunity is:

$50,000 - $40,000 = $10,000

The driver is the Club Channel , because Club has 25% ACV share but 30% Snack share. Club is 5 points over fair share, while AO Grocery is exactly aligned at 50% ACV share and 50% Snack share. Therefore, the most complete insight is that Mid-Mart is 5.0 points behind Total Store, the gap is driven by the Club Channel, and the opportunity is $10,000.
