Which of the following represents the correct order of acidity in the given compounds?

(a) F${\mathrm{CH}}_{2}$COOH > ${\mathrm{CH}}_{3}$COOH > Br${\mathrm{CH}}_{2}$COOH > Cl${\mathrm{CH}}_{2}$COOH

(b) Br${\mathrm{CH}}_{2}$COOH > Cl${\mathrm{CH}}_{2}$COOH > F${\mathrm{CH}}_{2}$COOH > ${\mathrm{CH}}_{3}$COOH

(c) F${\mathrm{CH}}_{2}$COOH > Cl${\mathrm{CH}}_{2}$COOH > Br${\mathrm{CH}}_{2}$COOH > ${\mathrm{CH}}_{3}$COOH

(d) ${\mathrm{CH}}_{3}$COOH > Br${\mathrm{CH}}_{2}$COOH > Cl${\mathrm{CH}}_{2}$COOH > F${\mathrm{CH}}_{2}$COOH

(c) The acidity of halogenated acid increases with increase in electronegativity of the halogen present. So,  the correct order is order is F > Ce >Br

F${\mathrm{CH}}_{2}$COOH > Cl${\mathrm{CH}}_{2}$COOH > Br${\mathrm{CH}}_{2}$COOH > ${\mathrm{CH}}_{3}$COOH
