The Calex Telecommunications Company is planning to introduce cellular telephone service into isolated coastal areas of Caladia, a move which will require considerable investment.  However, the only significant economic activity in these areas is small-scale coffee farming, and none of the coffee farmers make enough money to afford the monthly service fees that Calex would have to charge to make a profit.  Nevertheless, Calex contends that making the service available to these farmers will be profitable.

Which of the following, if true, provides the strongest support for Calex's contention?

(A) Currently, Caladian coffee farmers are forced to sell their coffee to local buyers at whatever price those buyers choose to pay because the farmers are unable to remain in contact with outside buyers who generally offer higher prices.

(B) In the coastal areas of Caladia where Calex proposes to introduce cellular telephone service, there is currently no fixed-line telephone service because fixed-line companies do not believe that they could recoup their investment.

(C) A cellular telephone company can break even with a considerably smaller number of subscribers than a fixed-line company can, even in areas such as the Caladian coast, where there is no difficult terrain to drive up the costs of installing fixed lines.

(D) Calex bases its monthly fees for cellular telephone service in a given region partly on the cost of installing the necessary equipment to provide the service there.

(E) Calex has for years made a profit on cellular telephone service in Caladia's capital city, which is not far from the coastal region.

用排除法作出了答案A，但总觉A和原文逻辑链缺了什么

原文说：尽管那个岛上的潜在客户付不起电信公司装移动网络的服务费，但是电信公司认为还是能够挣钱

A说：现在潜在客户只能低价卖货，于是如果有了手机－>能够与外界客户联系->价格可能卖高->然后开始付的起移动运营商的服务费)。

到底是为什么呀？

明白了

谢谢
