Solve the problem.Recent research has shown that the population f(S) of cod in the North Sea next year as a function of this year's population S (measured in thousands of tons) can be described by the Shepherd model, f(S) = 
where a, b, and c are constants. The values of a, b, and c are 3.036, 250.04, and 3.29, respectively. Find the approximate value of this year's population that maximizes next year's population using this model.
A. 194 tons B. 194,000 tons C. 4000 tons D. 161,000 tons
