$$\begin{array} { | c | c | c | } \hline \begin{array} { c } \text { Amount of Real Output } \\\text { Demanded }\end{array} & \text { Price Level (Index Value) } & \begin{array} { c } \text { Amount of Real Output } \\\text { Supplied }\end{array} \\\hline \$ 200 & 300 & \$ 500 \\\hline 300 & 250 & 450 \\\hline 400 & 200 & 400 \\\hline 500 & 150 & 300 \\\hline 600 & 100 & 200 \\\hline\end{array}$$ The table gives aggregate demand and supply schedules for a hypothetical economy. If the price level is 250 and producers supply $450 of real output,

A) a shortage of real output of $150 will occur.
B) a shortage of real output of $100 will occur.
C) a surplus of real output of $150 will occur.
D) neither a shortage nor a surplus of real output will occur.
