母親は嫌な顔ひとつしなかったが、娘の食生活がどんどん変になっていく _______ 困っていた。

And answers are:

のには 
 のから 
 のでは 
 のとは

The correct one is のには, but I don't understand why.

2

the の of のには in this sentence is attached to なっていく to form なっていくの which is equivalent to なっていくこと the に means "by" and the は is a topic marker, and together they refer back to なっていくの and means that this is what is causing her to have become 困っていた。

Hahaoya wa iyana kao hitotsu shinakatta ga, musume no shokuseikatsu ga dondon hen ni natteikuno ni wa komatteita.

A Japanese native will probably come along in a bit and give more detail, but I hope my explanation is understandable.
