Mary Granola Consumes Apples and Uglifruits

Mary Granola consumes apples and uglifruits.Mary's indifference curves are kinky.When she is consuming more apples than uglifruits, she is just willing to trade 3 apples for 1 uglifruit.When she is consuming more uglifruits than apples, she is just willing to trade 4 uglifruits for 1 apple.Let P₁ be the price of uglifruits and P₂ the price of apples.Mary maximizes her utility subject to her budget constraint.(Hint: Sketch one of her indifference curves.)

A) When P₁ >3P₂, she must consume only apples.
B) When P₁ > P₂, she must consume 3 times as many apples as uglifruits.
C) When 4P₁ >P₂, she must consume only uglifruits.
D) When P₁ >P₂, she must consume only apples.
E) She must consume equal numbers of both.
