The diagrams show the demand curves for the only two buyers in a market. [Two diagrams: left shows a straight downward-sloping demand curve from price axis to quantity axis; right shows a kinked downward-sloping demand curve from price axis to quantity axis.] What will be the shape of the market demand curve for the good?

1. A[Diagram: straight downward-sloping demand curve from price axis to quantity axis] price / quantity / O
2. B[Diagram: downward-sloping demand curve that becomes horizontal at lower prices] price / quantity / O
3. C[Diagram: kinked downward-sloping demand curve, steeper at lower prices] price / quantity / O
4. D[Diagram: kinked downward-sloping demand curve, flatter at lower prices] price / quantity / O
