I'll be glad to check your answer.

To evaluate possible product-market strategic plans using the total profit approach, we need to understand the different options mentioned in the question.

a. The statement "the total profit approach is the best approach to use" is a subjective statement and may vary depending on the specific context and goals of the evaluation. Therefore, it cannot be universally stated that it is the best approach to use.

b. The total profit approach can be used to compare possible plans even if they are not very similar, as it takes into account the overall profitability of each plan.

c. The total profit approach may support a plan that is not the most profitable in the short run because it considers the long-term profitability and sustainability of the plan, rather than just short-term gains.

d. To use the total profit approach, sales forecasts for the life of the possible plans are required. By forecasting sales, we can estimate the revenue generated by each plan and calculate the total profit.

e. Considering the explanations above, the correct answer is option c. The total profit approach may support a plan that is not the most profitable in the short run.
