The correct answer is: D. Both B and C.

Standard costing is a technique that uses pre-determined costs to compare actual costs and identify variances. It is often used in large companies with complex operations, but it can also be used in small businesses. However, there are some situations where standard costing may not be applicable, such as when:

• The company’s operations are very complex and difficult to standardize.
• The company’s products or services are constantly changing.
• The company’s costs are highly variable.
• The company’s management does not have the time or resources to implement and maintain a standard costing system.

In these cases, it may be more difficult or expensive to implement a standard costing system than the benefits it would provide.
