Question

A change from an inefficient mix to an efficient mix of output would best be represented with a production possibilities frontier (ppf) as a:

Answer 1

It would be best presented as movement from inside the PPF onto the PPF
The curve of The production possibility frontier (PPF) will show the curve that project/depict the possibilities for maximum output possibilities for two different goods. The projection that shown by the PPF is created with the assumptions that all resources are used efficiently.
