Answer : Carboxylic Acid mcq option image

Solution :
Alkaline $$KMn{O_4}$$ converts complete carbon chain ( that is directly attached to benzene nucleus ) to $$-COOH$$ group. $$B{r_2}$$ in the presence of halogen carrier causes bromination by electrophilic substitution reaction and ethyl alcohol in acidic medium results in esterification.
