children should be instructed to put things ( )they belong A where B in which C to which

题目

children should be instructed to put things ( )they belong A where B in which C to which
为什么不选B和C 不是 belong to 吗?
children should be instructed to put things ( )they belong in their childhood

答案

你说的对,是 belong to,所以肯定不选 B.至于为什么不选C,如果选C了,那么which在这里是什么成分?其实这句话的原句是：...to put things (in the place to which) they belong .这里的 where 就是代替 in the place to...
