The right answer is A.
Lactic fermentation is a catabolic process, a fermentation, having as a starting point glycolysis, which produces an acid, lactic acid used to reoxidize NADH to NAD+, and by the way it produces energy in form of ATP.
In other words, lactic acid fermentation is a biological process by which sugars such as glucose, fructose, and sucrose are converted into cellular energy and metabolic byproduct, lactate. It is a lactic ferment that intervenes.

<span>because “Barrow is ground zero for climate-change science, and because we worry that climate change is shrinking the sea ice and we don’t know how that will affect the animals that depend on it. But at this time there is no effective plan if a catastrophe such as a ship collision or oil spill occurs. The Coast Guard hasn’t decided what its presence will be in the Arctic. Someone needs to monitor whats going on there.</span>
