Solution

The correct option is A 1
Because of this resonance in carboxylic acid group, the >C = O bond length becomes 123 pm which is lesser compare to alcohols (143 pm) and more than ketones (120 pm). The Carbon-oxygen bond length on hydroxyl group side is around 136 pm which is more than >C = O due to lack of double bond.
