Answer 1

The correct choice is (a) Fluidized bed freezer

Easy explanation: Fluidized bed freezer is used to freeze particulate foods like peas, cut corn. The foods are placed on a mesh and moved through a freezing zone where cold air in upward direction is directed through the mesh belt and the food particulates begin to float. This leads to uniform freezing in all directions.
