Answer is Wrong!
Answer is Right!
The correct answer is: narrow.
A narrow thing is limited in scope or extent. It is not broad or wide. A universal thing is applicable to or valid for everyone or everything. It is not limited to a particular group or area.
The other options are not antonyms of universal.
A regional thing is limited to a particular region or area. It is not universal.
A miniature thing is small in size or scale. It is not large or extensive.
A subsidiary thing is subordinate or secondary to something else. It is not primary or principal.
