Answer :option 3 is correct
Amphibolic is used to describe a biochemical pathway that involves both catabolism and anabolism.
Respiration is catabolic process because it breaks complex organic compounds into simple organic compounds for ultimate formation of ATP. Respiration is also anabolic process as it provides many intermediates for biosynthesis of complex organic compounds like fat, proteins, etc.So we can say respiration is Amphibolic because it involves both catabolism and anabolism processes.
