A good example of a company that uses direct sales strategy would be: Select one:

Boeing would use a direct sales strategy, as their product is high value and specialized. 

If I am not wrong, I think it is Boeing (C)

The answer is c. Boeing as the top in B2C.

Common types of direct sales are those you sell over the counter to your customer, through direct mail marketing or selling on a website, such as Amazon.com or even your own site

Direct sales means going straight to your customer and selling her your product. You can phone the customer, see her face to face or even use email. The communication link between the company and the prospective customer is direct. Direct is also known as B2C or "business to consumer." When engaging in indirect sales, a company uses some type of go-between and does not directly contact the customer. The go-between could be a reseller, a commissioned independent sales agency or even another distributor. Indirect is also known as B2B or business to business.

Agreed with all the above answers

Products that are typically sold with direct sales include: aircraft, infrastructure projects (highway construction, power plant construction etc), complex technology solutions (ERP packages, large servers, IT projects). All of these demand a detailing and hand holding and the sales process itself is long and complex. High value machinery sold by Bhel for example, has to be explained in detail to the customer. L & T assists with technical support through the life of the equipment. Customer Support Contact Centres assist through emails and voice calls and they thus need to be in constant touch with the customer. IBM’s declared Selling Objectives are to create customer value at every stage in the buying process, create and leverage the synergy of the sales team and improve the speed and quality of the sales process through direct selling.

Boeing wold be a direct sales strategy 

>>>>>> My answer will be option c. Boeing .

As All other Said it will be Boeing 

answer C: i think that Boeing is very good 

BOEING is the only logical answer as all others are in the retail business.

Most successful retail businesses irrespective of FMCG or Whitegoods inevitably are high volume and cannot meet their volumes without the distributor-retail channel supply chain. (AMWAY being an exception but it's volumes are nowhere near HLL or LG)

BOEING on the other hand is in the high value, technology intensive aircraft manufacturing industry. Moreover this industry has high entry barriers and few competitors and customers(airlines).

As such among the given choices only Boeing can successfully use the direct selling strategy.
