Solution

The correct option is D intramolecular redox
Intermolecular redox reactions: In which one substance is oxidised while the other is reduced.
Intramolecular redox reactions: In which one element of a compound is oxidised while the other is reduced.
$(N H_{4})_{2} C r_{2} O_{7} \to N_{2} + C r_{2} O_{3} + 4 H_{2} O$
-3 +6 0 +3
Hence, the reaction is an example of intramolecular redox reaction.
