Use the following information about demand and supply schedules to answer the question.
$\begin{array}{ccccc} \text{Price} & D1 & D2 & S1 & S2 \\\hline\$ 12 & 5 & 9 & 19 & 14 \\\$ 10& 8 & 12 & 17 & 12 \\\$ 8 & 11 & 15 & 15 & 10 \\\$ 6 & 13 & 18 & 13 & 8 \\\$ 4 & 16 & 21 & 11 & 6 \\\$ 2 & 18 & 24 & 9 & 4\end{array}$
-Refer to Exhibit. Suppose that D₂ and S₁ are the prevailing demand and supply curves for a product. If the demand schedule changes from D₂ to D₁, then:

A) equilibrium price decreases from $6 to $4.
B) equilibrium quantity decreases from 15 to 13.
C) equilibrium quantity increases from 13 to 18.
D) equilibrium price increases from $6 to $8.
