Which root means 'nitrogen waste'?

Explanation:
Nitrogenous waste is the focus, so the root that fits is azot/o. This combining form is used in medical terms to refer to nitrogen-containing waste products produced from protein breakdown and cleared by the kidneys, such as in azotemia (nitrogen in the blood) or azoturia (nitrogenous waste in urine). That connection to nitrogen waste is why this root is correct. The other roots map to entirely different ideas—glycos/o to sugar, bi/o to life or two, vesicul/o to a vesicle or seminal vesicle—so they don’t carry the meaning of nitrogen waste.
