Figure: Monopolistic Competition $3$Two graphs show the M R$,$ M C$,$ and D lines for markets A and B$.$ In the graph for market A$,$ the vertical axis represents P and marks the values $5,7,$ and $10$ dollars. The horizontal axis represents Q and marks the values $90,125,$ and $180.$ A negative sloping line labeled D starts from a point above $10$ dollars on the vertical axis. Another line labeled M R starts from the same point as line D and has a steeper negative slope than line D$.$ A horizontal line labeled M C starts from $5$ dollars on the vertical axis. M C equals A C$.$ Two points on line D correspond to $(90,10)$ and $(125,7)$ as denoted by dashed lines. The line D intersects M C at $(180,5)$ as denoted by dashed lines. M R intersects M C at $(90,5)$ as denoted by dashed lines. The monopolistically competitive firm in this diagram is in $\_\_\_\_\_$ equilibrium and charging a price of $\_\_\_\_\_.$Group of answer choicesshort$-$run; $$11$long$-$run; $$14$long$-$run; $$8$short$-$run; $$8$
