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 find the slope of a straight line tangent to point B. This will give us the rate of change of yield per acre with respect to fertilizer applied at that specific point, which is the definition of marginal response.
