Solution

The correct option is D Both Assertion and Reason are incorrect
A weak acid will react with a strong base to form a basic (pH>7) solution.
Phenolphthalein is a suitable indicator for this titration. Methyl orange is not suitable for this titration because its pH range lies on the flat portion of the curve.
