Answer:
The committee debates how to fund their ambitious plans
Explanation:
The underlined word should be "The committee debate how to fund their ambitious plans".
If so, then the type of error present in the sentence is that a collective noun uses the plural verb "debate" which is wrong.
It can be fixed by giving it a singular verb "debates" and rewritten as "The committee debates how to fund their ambitious plans"
The last one is correct i think
