If all the resources are used in the production of cloth, the curve which gives the maximum amount of cloth produced in the economy for any given…

Option 1 -> Represents all feasible production combinations (a set/area), not just the maximum boundary.

Option 2 -> Shows the maximum output achievable when all resources are fully and efficiently utilized.

Option 3 -> Shows combinations of inputs that produce the same output level, not maximum production boundaries.

Option 4 -> Represents consumer preferences, not production capabilities.

---

Hence, Production Possibility Frontier -> The PPF is the boundary curve that represents the maximum possible production combinations when all resources in the economy are fully and efficiently employed. It shows the maximum amount of one good (cloth) that can be produced for any given quantity of another input (machines) or output, assuming optimal resource allocation. Points on the PPF indicate efficient production, while points inside represent underutilization of resources. -> correct
