Hello Student,
Please find the answer to your question
(c) TIPS / Formulae:
(i) The inductive effect decreases with increase in distance of halogen atom from the carboxylic group and hence the strength of acid proportionally decreases.
(ii) The acidity increases with the increase in electronegativity of the halogen present.
Smallest dissociation constant means weakest acid, which is BrCH2 CH2OOH because here Br (less electronegative than F ) is two carbon atoms away from –COOH.

Thanks
