Which three are Cost accounting methods'

[: Oracle SCM Cloud Cost Management Guide explains how Perpetual Average Cost is maintained and updated across transactions., Statement C:Frozen Standard Cost– This method involves predefining a standard cost for each item at the beginning of a financial period. The cost remains "frozen" throughout the period, and variances between the actual cost and the standard cost are tracked and analyzed separately., Reference: Oracle Costing Methods documentation specifies that the Frozen Standard Cost method is particularly useful for manufacturers who need stable cost inputs over a financial period., Statement D:Actual Cost, also known as "FIFO"– The FIFO (First In, First Out) method records costs based on the order in which items are received. It is a type of actual costing where items are valued based on the specific costs of the earliest received inventory. Oracle Cloud supports FIFO as part of its actual costing methods., Reference: Oracle Cost Accounting documentation details the use of FIFO for tracking actual costs in a layered costing approach., Incorrect Statements:, Statement B:Layer Cost, also known as "LIFO"– Oracle Cloud does not natively support LIFO (Last In, First Out) as a cost method due to accounting and regulatory restrictions in various regions. LIFO is generally not used in the system as a standard method., Statement E:Periodic Actual Cost– While there is a method called Periodic Average Cost, Periodic Actual Cost is not typically listed as a standard costing method in Oracle Cloud., , ]
