Final answer:
The perceived demand curve for a monopolist is downward sloping and reflects the overall market demand curve since the monopolist is the sole producer, making option (c) correct; this curve is also less elastic compared to that of monopolistically competitive firms.
Step-by-step explanation:
The perceived demand curve for a monopolist reflects the market demand curve for its product, since the monopolist is the only producer in the market. In contrast, a perfectly competitive firm perceives a flat demand curve because it faces a market with many other firms and can only be a price taker. Hence, the monopolist's perceived demand curve is indeed downward sloping, as it can set different prices for different quantities, making option (c) correct. However, unlike a monopolistically competitive firm's demand curve, which is more elastic due to the presence of direct competition, the monopolist's demand curve is relatively inelastic. The monopolist will seek to maximize profits by finding the output level where marginal revenue equals marginal cost and will set the corresponding price as indicated by the demand curve. Therefore, option (d) is not correct because the monopolist's perceived demand curve is not the same as the market demand curve; it is the market demand curve directly.
