Answer to Question 1

B

Answer to Question 2

In a competitive market, producers choose an output level where marginal cost equals price. Thus Px/Py = MCx/MCy. Each consumer maximizes her own utility subject to the given prices by setting MUx/MUy = px/py. Even though each is acting independently and in her own interest, the final outcome is that px/py = MRS = MRT, which is the condition for efficient product mix.
