Which of the option is correctly given in the decreasing order of acidity of the organic acids ?

2,4,6 – trinitro phenol commonly known as picric acid is stronger than all of the other acids given. This is due to high -I effect of the nitro group. Then comes the ortho substituted carboxylic acids due to −NO2  groups are strong – I groups. o-methoxy is greater than simple benzoic acid due to -I of oxygen or can be explained by ortho effect.Pka  values, 2,4,6 – trinitrophenol  pka=0.67  o – nitro benzoic acid  pka=2.16  o – methoxy benzoic acid  pka=4.09  Benzoic acid   Pka=4.16
