B. she is confusing between price elasticity of demand and income elasticity of demand.

Explanation:

Income elasticity of demand measures the change of quantities demanded for a particular good to a change in its income.

It is therefore calculated as the ratio of the percentage change in quantity demanded to the percentage change in income.

Price elasticity of demand is a measure of the change in the quantity demanded or purchased of a product in relation to its price change.

Mathematically:

Price Elasticity of Demand = % Change in Quantity Demand / % Change in Price.

From the above definitions stated about income and price elasticity of demand, the income in that year increased but the quantity of goods demanded decreased further by 5% from the predicted 7% (12 %)
