Answer:
Option "D" is the correct answer to the following question
Step-by-step explanation:
Marginal utility of A / Price of A = Marginal utility of B / Price of B
MU(a) / P(a) = MU(b) / P(b) , for maximum utility.
At the maximal point, the gradient of the separate budget is equal to the slope of the production possibilities. The production possibility slope is the nominal value of A / the nominal value of B.
