Hi there!
So, we know that your looking for the word that has the same denotative meaning as refute. Well based on the definition itself.
Refute: prove (a statement or theory) to be wrong or false; disprove.
This however should lead you to the answer of:
Support: give assistance to, especially financially; enable to function or act.
Hope this helps and have a fantastic day!
