have been helping是现在完成进行时的用法.表示从过去开始一直进行着直至现在.

They have helped (help)us since five this morning until now.
这是一个现在完成时的句子，表示从过去开始一直持续到现在，并对现在有影响。

have helped.
现在完成时.过去动作持续到现在

had been helping,过去完成时，因为是一个持续的动作，并且是过去开始做的，这段时间一直在帮忙所以用ing.

答案是have helped,题目中“until now”意思是知道现在，说明他们帮助我们并且现在还在帮助，所以应该用现在完成式have been结构

until now 是多余的。
