What's the difference between 関{かん}する and 関{かか}わる?


This question is in my JLPT practise book:

> 親{おや}のしつけが子供{こども}の性格{せいかく}形成{けいせい}に＿＿＿＿ことは言{い}うまでもない。
>
> **A** 通{つう}じる **B** 通{とお}す **C** 関{かん}する **D** 関{かか}わる

The book says the answer is **D** , but to me the definitions of **C** and
**D** overlap so much that I can't see why one is obviously better.

So what's the difference between `関{かん}する` and `関{かか}わる`?




Both Xに関する and Xに関わる have the overlapping meaning when it comes to 'concerning
or related to X'.

However when you see XがYに関わる or Yに関わるX it is probably better than 関する when X
is something that directly affects Y, or is something that Y is dependent
upon. Also, there is the nuance that Y is a big or serious thing such as
education, peace, life.

For example you might say 治安に関わる仕事 when talking about policemen to show the
large degree in which peace (public order) is a result of the police.

You may also say 治安に関する仕事 but then it's means more something like a job that
has something kind of connection to peace, and would not be as complimenting
as the above example.
