10 mL of a solution of NaOH is found to be completely neutralized by 8 mL of a given solution of HCl. If we take 20 mL of the same solution of NaOH, the amount of HCl solution (the same solution as before) required to neutralize it will be

Correct option is E

The correct answer is None of the above.
8 mL of HCl solution is required to neutralise 10 mL of NaOH.
So as usual to neutralise 20 mL of same solution i.e. of NaOH we would need 16 mL of same solution of HCl.
