The correct acidity order of the following is

Carboxylic acid is more acidic than phenol. When an electron releasing group is present in the para position to -COOH group in aromatic carboxylic acid, the acidity is reduced. When Cl atom is present in the para position to -OH group in phenol, it increases its acidity because -Cl  withdraws electron density from the ring and stabilizes the phenoxide ion.
