To determine the marginal response of "yield per acre" due to a change in "fertilizer applied per acre of wheat" at point B, we need to calculate the slope of the tangent line to point B on the production function curve. This will give us the instantaneous rate of change of output with respect to fertilizer applied at point B, which is the definition of the marginal product.
