首先纠正一下,并不是所有to后面都加动词原形.
只有to作为动词不定式标志的时候,后面加动词原形.
而如果to是一个介词,后面一定要加doing.
这一题中to就是介词.make a contribution to doing是一个固定短语.
另外,contribution是可数名词,在这个句子中应该是contributions,我不明白为什么少了个s,你看看是不是抄错了.

此处TO当介词，规定接名词（动名词）。

应该是A呀,你的答案错了

对...有所贡献
to 是介词，后面是名词性的。

contribution to 对…的贡献。。…是名词。所以helping the poor 选动名词

此处的TO不是动词不定式TO DO的形式,它在此句中翻译成"为了".尽管这家公司的资金很多,但是它的破产是因为对穷困人民的捐助.

to在此是介词，后面需加ing形式。还有一些类似的，例如：look forward to doing,get down to doing.
