Solution

The correct option is B $- C O O H, - {S O}_{3} H, - {C O N H}_{2}, - C H O$
1) $- C O O H, - S O_{3} H, - C O N H_{2}, - C H O$

2) Order of priority for other functional group is given as

carboxylic acid > esters > amide > nitrile>aldehydes > ketones > alcohol > amines > hydrocarbons > ethers > alkylhalides.
