Companies started to set prices by considering the whole marketing mix rather than just the product itself. In this way, profits can be maximized. There are different product mix pricing strategies including product line pricing, byproduct pricing, optional-product pricing, captiveproduct pricing and product bundle pricing. In product line pricing, company sets different prices for the products in line. For example three different price levels may be set for three models of basic t-shirts. By-product pricing involves products produced unintentionally as an output of the manufacturing process of the main product. These kinds of products have no (or little) value such as sawdust. Optional-product pricing refers to accessory products sold with the main product. For example, consumers may buy steel rims or parking sensor along with a car. Captive-product pricing refers to complementary products which are used with the main product such as printer cartridge, so the company may get higher profits from the sales of cartridges. In product bundle pricing, less demanded products are sold together with highly demanded ones at a discounted price. The aim of the strategy is to promote less demanded products. B is the right answer.
