We are the best friends,____we often have some different ideas A because B but C and D though

问题描述:

We are the best friends,____we often have some different ideas A because B but C and D though

选D
A选项明显是错误的,该句不是因果关系
B选项but虽然是转折关系,但是前面有逗号,不能用
C选项中显然也是错误的,这里也不是并列关系
D选项说准了并列关系,句意也对,前面可有逗号
评价分析的应该不错,希望选为满意答案
