Solution

The correct option is B
Temperature is an intensive property that is independent of the amount of substance.
Not convinced?
If $x J$ of heat is released when 50 cc of acid and base react, then $5 x J$ would be released when 250 cc of the same acid and base react, right?
Also the amount of the solution has also become 5 times!
You know that $q = m C Δ T$
Since $q$ and $m$ increase by the same ratio, $Δ T$ is the same!
