This is Auditing. Please provide me the answers ASAP. Thank you very much!

Western Manufacturing Company (WESMA) is planning to acquire Crystal Producer Inc. (CPI), a small manufacturing company that produces related products which will align with WESMA's vertical integration strategy. WESMA has examined the financial statements of CPI, which show only a relatively small profit in the last five years. Management of CPI has taken reasonable salaries, and CPI's cost of goods sold is higher than the industry average. WESMA believes that it will be able to introduce operational efficiencies at CPI, improving the profitability of the small company, if successfully acquired. Required: A) What type of engagement should be conducted to assess the operational efficiencies of CPI? Justify your response. B) Who should be engaged to conduct the engagement? C) What major problems might the auditors encounter when conducting the audit and writing the report
