The components of physical distribution are:

Order-processing, inventory control, warehousing and transportation

The correct answer is option 2- Order-processing, inventory control, warehousing and transportation.

Physical Distribution: There are two important decisions relating to this aspect one regarding physical movement of goods and two, regarding the channels. Physical Distribution covers all the activities required to physically move goods from manufacturers to the customers. The main component of physical distribution are (i) Order Processing; (ii) Transportation; (iii) Warehousing; and (iv). Inventory Control: Just-in-Time-Inventory.

Order Processing: In a typical buyer-seller relationship, order placement is the first step. Products flow from manufacturers to customers via channel members while orders flow in the reverse direction, from customers to the manufacturers. A good physical distribution system should provide for an accurate and speedy processing of orders, in the absence of which, goods would reach the customers late or in wrong quantity or specifications. This would result in customer dissatisfaction, with the danger of loss of business and goodwill.

Transportation: Transportation is the means of carrying goods and raw materials from the point of production to the point of sale. It is one of the major elements in the physical distribution of goods. It is important because unless the goods are physically made available, the sale cannot be completed.

Warehousing: Warehousing refers to the act of storing and assorting products in order to create time utility in them. The basic purpose of warehousing activities is to arrange placement of goods and provide facilities to store them. 

Inventory Control: Linked to warehousing decisions are the inventory decisions which hold key to success for many manufacturers, especially those where the per unit cost is high. A very important decision in respect of inventory is deciding about the level of inventory. Higher the level of inventory, higher will be the level of service to customers but the cost of carrying the inventory will also be high because lot of capital would be tied up in the stock. Thus, a balance is to be maintained in respect of the cost and customer satisfaction.
