C) price.
Manufacturing companies compete primarily on price, as they offer similar products or services to customers and try to differentiate themselves by offering lower prices or better value than their competitors. This is done by reducing costs through economies of scale, improving efficiency, using cheaper inputs and raw materials, or through technology or process improvements that allow them to produce goods or services more cheaply. By offering a lower price, the companies can attract and retain customers, grow their market share and increase their revenue.
