Answer:
D. demand is unitary elastic.
Explanation:
A unitary elastic demand means that the quantity demanded will change proportionally to any change in the price of the product or service. E.g. price decreases by 10%, then quantity demanded will increase by 10%.
The marginal revenue curve represents the additional revenue generated by selling one more unit. As the marginal revenue curve approaches 0, it means that selling one additional unit generates lower revenues.

At the price equilibrium of $600, the number of renters would exactly meet the number of available 2 bedroom apartments. However, with this fixed price ceiling, the position along the demand curve will shift to one of higher demand, with no analogous change in the supply curve. Thus there will be more renters than can be supported, and renters will have to look for alternatives and substitutes.</span>
