The correct answer is: B
The assembly line, or production line, forms the basis of the chain production system. It is a system in which the productive process tries to optimize costs, minimizing the loss of time and promoting the maximum specialization of the worker and the division of labor. Thus, each worker in the assembly line performs a specific operation on the product in progress, which then passes to the next worker, and so on, until the end of the assembly line is completed.
