D
句意是“很抱歉,我真的不知道怎样修理这个钟.”
how to do sth 怎样做某事,是固定搭配
A,C与句意不符.
B 可以改为 how I should mend

Dwhy?know后面不能直接加不定式，所以A不对。 know后面加的宾语从句应该用陈述语序，所以B不对，应该是how I should mend. CD两项的差别在于how和what，____修表，“什么/怎样”中选择，很明显，应选how. how to mend the clock在这里就相当于how I should mend the clock....

i'm sorry ,I really don't know ( )the clock
选D。I‘m sorry, I really don’t know how to mend the clock
不好意思，我真的不会修钟表。

选D
从全句的意思看，“我很抱歉，我真得不知道该如何修理这个钟。”，因此疑问词选how，排除A和C。know后面引导宾语从句的话，必须是陈述句语序，B选项错
