Solution

The correct option is B 50:50
For max. rise in temperature,
Max. neutralization of $H^{+}$ and $O H^{-}$ required.
If we take equal volume, all $H^{+} (0.1 M)$ will react with all $O H^{-} (0.1 M)$ .

The correct option is B 50:50For max. rise in temperature, Max. neutralization of H+ and OH− required.If we take equal volume, all H+(0.1M) will react with all OH−(0.1M).
