Your answer: C was correct!
The only true statement listed in the question is that, under pure competition there are no barriers to entry into the market. Each of the other possible answers is incorrect. While the competitors can earn positive economic profits in the short-run, they cannot earn long term economic profits due to ease of entry and exit.
