Suppose the commodities can be purchased and consumed in discrete quantities only. Each of 1 x and 2 x axis is found to contain a point that fully exhaust the consumer’s budget. Then, which of the following is true?

Q.8 In deriving the Hicks substitution effect, the purchasing power of income is kept constant following a decline in the price of the commodity by

B. relegating the consumer to a lower indifference curve
C. enabling the consumer to purchase the same bundle of goods as before the
price-change
