Answer:
The correct answer is option E.
Explanation:
An increase in per capita GDP implies that the income of the consumers is increasing.
The demand for ABC baby food though has decreased. This means that this baby food is an inferior good.
In case of inferior good, income and demand are inversely related to each other. So an increase in income will cause the demand to decrease and vice versa.
The demand curve will move to the left as at the same price less quantity of baby food will be demanded now.
