• B. SF
• C. A

Answer: (A)

Flat metal plaster base is defined by its smooth, flat sheet form used as the base for plaster. This designation identifies the lath that provides a uniform, even surface for plaster to key to, without the openings or ridges found in other lath types. Expanded or ribbed lath create different patterns and mechanical keys, which are not the same as a flat base. So the designation that corresponds to a flat metal plaster base is the one that indicates a flat, smooth lath suitable for a level plaster finish.
