Arya only consumes two goods: X and Y. When the price of X changes, the income effect and the substitution effect for X move in opposite directions. In addition, the income effect for X dominates the substitution effect. X must be: a) a Giffen good for Arya. b) an inferior good for Arya. c) a normal good for Arya. O d) perfect substitutes for Arya. O e) Both a and b are true.
