Answer is attached below

Answer A The Marginal Costing is a technique where costs to inventory that were incurred when the units of each individual unit was produced, while in case of Absorption Costing all the Budgeted production costs are applied to all units produced. In a period, Overhead costs are charged as expense under the marginal costing. In the case of Absorption method, these costs are applied to products. Below are the benefits of using marginal costing over absorption costing . Constant in nature: Marginal Costs remain the same irrespective of production. These are stable. Effective Cost Control: Here, Both the costs are divided, i.e., Fixed and variable. Fixed are period costs and thus excluded from the product. As such, the management can easily control the marginal cost very effectively. Treatment of Overheads simplified: There is a reduction of over or under-recovery of Overheads costs due to fixed overheads are separated from the production costs.
