Solution

The correct option is D $C O N H_{2} > C O C H_{3} > C H O > C H_{2} O H$
While assigning R, S configuration the correct order of priority of groups attached to chiral carbon atom is $C O N H_{2} > C O C H_{3} > C H O > C H_{2} O H$
Atomic having higher atomic number has higher priority.
The decreasing order of atomic numbers is $O > N > C > H$
In $C O N H_{2}$ group, the $C$ atom is attached to 2 $O$ atoms and one $N$ atom.
In $C O C H_{3}$ group, the $C$ atom is attached to 2 $O$ atoms and one $C$ atom.
In $C H O$ group, the $C$ atom is attached to 2 $O$ atoms and one $H$ atom.
In $C H_{2} O H$ group, the $C$ atom is attached to 2 $H$ atoms and one $O$ atom.

Option B is correct.
