Correct option is A

Explanation:

Yes, because firms produce at the lowest average cost possible.

A perfectly competitive firm produces at MC=P=ATC in the long run, and productive efficiency is at a minimum of average total cost. An average total cost is a minimum where MC=P so the perfectly competitive markets are productively efficient in the long run.
