Use the following supply and demand graph to answer the question below. A graph depicts 2 supply and 2 demand curves intersecting each other.The horizontal axis from left to right lists labels as A, B, and C and is labeled quantity. The vertical axis from bottom to top lists labels as E, F, G, H, I, and J and is labeled price. Two parallel decreasing curves, D1 from I and D2 from J at the vertical axis intersect two parallel increasing curves, S1 from F and S2 from E at the vertical axis. Two dotted lines connect the point of intersection of D1 and S1 to A at the horizontal and B at the vertical axis. Two dotted lines connect the point of intersection of D2 and S1 to B at horizontal axis and H at vertical axis. A dotted line connects the point of intersection of D2 and S2 to C at the horizontal axis. All the data points connects to both the axes through dotted straight lines. S1 and D1 represent the current private market supply and demand, respectively. If D2 represents the social demand curve, what is the socially optimal level to produce
