The answer is (a)

The firm will maximize profits when,

Marginal revenue product of X = Price of X

=> PY * MPX = PX

=> MPX = PX/PY

All other options are incorrect as they do not maximize profits

Q2) The answer is (b) as initially when the inputs increase, there is increased efficiency and the output increases at an increasing rate. But eventually, the diminishing returns sets in and the output will increase at a decreasing rate and reach a maximum when marginal product of the input reached 0.
