English is used all over the world .Most of the calls ----in English People like to do business -------.
A.make ，using phones B.are made ，by phone C.are made ，with phone 为什么？

B
Most of the calls are made in English. "be+过去分词"是被动语态，
People like to do business by phone. by phone用电话，by表示方式，其实using phones 也可以，只是没有这一项。

楼主参考

B
用电话by phone
make calls
calls are made是被动

B
make the call所以用被动语态，calls are made。by phone用电话，by表示方式
