The diagram below shows a firm operating under conditions of monopolistic competition in the long run.

Which of the following statements is correct?
At the profit-maximising output Q1Q_1Q1, the firm is operating in the price-inelastic range of its demand curve.
The firm is productively efficient because it operates at the point where Average Cost (ACACAC) is tangent to the Average Revenue (ARARAR) curve.
The firm makes only normal profits because at the profit-maximising output Q1Q_1Q1, Average Revenue is equal to Average Cost (AR=ACAR = ACAR=AC).
The firm is allocatively efficient because it produces where Price equals Marginal Cost (P=MCP = MCP=MC).
