1.楼主所言极是,不能选A.
2.A having bitten其实是bitting的完成式.那就意味着句子主语the postman是该动作bit的主动发出者.
一不符合逻辑,“邮递员咬人”吗?
二则bitten后面没有宾语,“咬谁”呢?
3.如果要表示“已经被咬过两次”的话,的确如楼主所言,应该改成having been bitten才可以.

好像不对吧，化城完整的原因转语从句因该是The postman refused……,because he was bitten twice.或者he had been bitten twice.如果是前者，缩写成C选项，如果是后者，我觉得不能使having而是had吧，不好意思，学太久了，忘记了，不敢肯定，仅供参考

语法上是可以的，不过有时候虽然语法对但是不一定是人家的说话习惯~~

Having been bitten twice,the postman refused to deliver our letters unless we chained our dog up.可以的哎~~~~
