In plants, the main excretory product produced during metabolism is
- oxygen
- alkaloids
-
carbon(iv)oxide

The correct answer is: C
Explanation
The main excretory products of plants during metabolism are carbon dioxide, excess water, and nitrogenous compounds.
Plants produce carbon dioxide as a metabolic waste product during respiration, while oxygen is a metabolic waste product from photosynthesis. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. Oxygen released during photosynthesis is used for respiration while carbon dioxide released during respiration is used for photosynthesis.
