Assertion (A): A PPC is convex to the origin.
Reason (R): The marginal rate of transformation rises along a PPC.

Both A and R are true, and R is the correct explanation of A.Correct answerYour answerBoth A and R are true, but R is not the correct explanation of A.Correct answerYour answerA is true, but R is false.Correct answerYour answerA is false, but R is true.Correct answerYour answer

CorrectNot quiteAnswer D

Correct answer: D

A rising MRT makes the PPC concave (bowed out) to the origin, not convex, so A is false.
R is the standard reason for the PPC's shape and is true.

Worth noting

Convex to the origin describes an indifference curve, which has a falling MRS.
