3. Which of the following options is/are true about feasible frontiers? a. The point where the feasible frontier and indifference curve are tangent to each other showsthe combination of x

and y which gives the individual the highest utility under the constraint. b The feasible frontier shows all feasible combination of x and v for that particular individual c. The increasing mrt along the feasible frontier from left to right captures the idea of increasingopportunity cost. d. The negative of the slope of the feasible frontier is called the marginal rate oftransformation.
