B用了被动时态，A比B好。

B后半句的主句的时态是过去时（tried to），和前面、后面的一般现在时的时态不一致。所以把B排除。

弱弱地再问一个问题:try to do和try doing在用法上有什么区别么?

try to do: you try to do something, or try and do it, when you make an effort to do it, because you need to, or want to, do it;简单理解to attempt to do or get something.
try doing: to do or use something for a short while to discover if it is suitable, successful, enjoyable etc
