Answer:

c. will earn zero economic profits but positive accounting profits

Explanation:

A competitive industry is characterised by many buyers and sellers of homogenous goods and services.

There are no barriers to entry and exit of firms. If firms in a competitive industry earn economic profit in the short run, firms enter into the industry in the long run and economic profit falls to zero.

A competitive firm earns accounting profit but doesn't earn economic profit.

Accounting profit = Revenue - Cost

Economic profit = Accounting profit - Opportunity cost
