What does household penetration measure?

The correct answer is A .

Household penetration measures how many households purchased a product, brand, category, or retailer within a defined time period. CMKG explains that sales can be analyzed through Total Number of Buying Households , also called Penetration , multiplied by spend per household. CMKG further clarifies that penetration relates to the number of households purchasing the product.

Option A is therefore the exact definition. It measures the percentage of households that bought during the specified period.

Option B is wrong because new product introductions measure innovation or assortment activity, not household penetration. Option C describes purchase frequency, which measures how often buyers purchase. Option D describes revenue or dollar sales, not penetration. Household penetration is a buyer-base measure, not a sales-value measure.
