Marginal cost (MC) and marginal benefit (MB) are important considerations in economics as limited mean and unlimited wants are a basic characteristic of economic choice. Using the MC and MB curves on the chart provided, determine the condition being observed where the dotted line crosses the MB and MC curves? Two curves and a line on a coordinate plane. A coordinate plane has a horizontal axis labeled Environmental Protection and a vertical axis labeled Price. From left to right, a curve labeled M B falls at a decreasing rate. From left to right, a curve labeled M C rises at an increasing rate. A vertical dashed line crosses both curves to the right of the intersection of the curves. Select the correct answer below: At this point the benefit of continuing to spend is low as the MB of the spending is declining. Because the gap between marginal benefits and marginal costs in narrowing at this point, it is optimal to continue spending until optimization occurs. At this point, MC has exceeded MB, which means spending is disproportionate to benefit and it should be reconsidered
