Benzoic acid > formic acid > acetic acid
Because benzoic acid is resonance stabilised so the -COOH group is most stable there. So it’s got the highest acidity.
Between formic and acetic acid, the smaller alkyl group the higher the acid strength (I effect)

The acidity order is H-COOH>Ph-COOH>CH3-COOH. This clearly indicates that formic acid is a stronger acid than benzoic acid.
