Answer:
a.Work in Process and Finished Goods
Step-by-step explanation:
The summary of materials requisitions shows all request for raw materials used for production.
When raw materials are obtained, they go into the factory where production begins. Raw material is converted to finished goods which are then sold.
The inventory that represents raw materials received in the factory is Work in progress and finished goods.
So when transferring cost of materials it should be transfered to work in progress and finished goods, as these accurately represent the converted raw material recieved.
