An economy produces agricultural output and industrial machinery, as represented by the production possibility frontier (PPF) diagram below.

Which of the following statements can be correctly inferred from the diagram?
Points MMM and NNN are both productively efficient, while Point UUU represents allocative inefficiency.
Point VVV is currently unattainable, and Point MMM is allocatively efficient because it prioritizes essential agricultural output.
Points MMM and NNN are both productively efficient, but we cannot determine which point, if either, is allocatively efficient.
Point UUU represents a state of full resource employment, while Point VVV represents a point of maximum allocative efficiency.
