Answer :
The correct answer is B. The assembly-line production is a process using workers to construct products more efficiently by dividing labor into specialized tasks.
An assembly line is generally constituted by a belt, called a conveyor belt, which slides carrying the different objects to be assembled to obtain the finished product; each worker can thus assemble a single piece, through repetitive and mechanical movements, allowing a considerable saving in production times: since this method went into operation, in the Ford factory, the time needed to produce a single car was reduced by 12 hours to just 1 hour.
