Cost reports for the intention of management should reflect?

Cost reports for the intention of management should reflect cost and comparable data useful in decision-making. This means that management should receive reports that provide information that will help them make informed decisions about the organization's operations. The reports should include detailed information on costs, including both controllable and non-controllable expenses, as well as comparisons with industry benchmarks and other relevant data. This will allow management to identify areas where costs are high and take corrective action, as well as identify areas where the organization is performing well and make decisions that will help maintain or improve that performance. Therefore, the option that best reflects this idea is "cost and comparable data useful in decision-making".
