The correct answer is d) negatively sloped and relatively steep.
The demand curve for a monopolist reflects the relationship between the price of the product and the quantity demanded. In a monopolistic market, the monopolist is the sole producer of a good or service, and they face the market demand curve, which is typically downward sloping. This means that as the price of the product decreases, the quantity demanded increases.
A steep demand curve indicates that the quantity demanded does not change significantly with small price changes, which is often the case in monopolistic markets where there are few or no close substitutes for the product. As a result, the monopolist can set higher prices without losing a considerable number of customers.
