Unless I receive a satisfactoryresponse from you within a month，

，I shall put this matter ____ my lawyer's_____.
a)on...hand
b)off...hands
c)at...hand
d)in...hands

选哪一个？如何区分这几个？
选a还是d?

Unless I receive a satisfactory response from you within a month,I shall put this matter in my lawyer's hands.

其实这一题就是考put和介词的搭配:
put on: v.穿上,把...放在上,装出,假装,增加,欺骗,添上,使靠...维持生命
put off: v.推迟,拖延,搪塞,使分心,使厌恶,扔掉,脱掉,劝阻
put at: vt.把...置于,估量作,放在...前面
put in: v.放进,提出,提交,插入,进入,使就职,种植,进港
