Final answer:
The correct answer is (b) Stationary layout, which is used in situations where the product doesn't move throughout the production process.
Step-by-step explanation:
When a work center has a fixed layout where the product remains in place for the duration of production, this type of layout is referred to as a stationary layout. A stationary layout is often used in industries where the product is too large or heavy to move, such as shipbuilding or aircraft manufacturing. The design of this layout helps to create a mechanized work environment that allows for the production of identical products in every location. It facilitates the work of specialized labor and machinery to come to the stationary product, which remains in a central workspace throughout the entire production process.
