Answer:
A. The bacteria are breaking down sugars in the absence of oxygen.
Explanation:
Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers.
They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen.
In Glycolysis:
2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.
Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.

D
Explanation:
Prokaryotes do not have a nucleus or membrane bound organelles.
Answer:
No, the viruses are not considered as cells.
They are not considered as living cells as they can not do anything outside the cell.
They are obligate parasites which can not survive in absence of any host.
They are considered as complex assemblies of molecules such as nucleic acid, proteins, lipids et cetera.
Thus, they also do not follow any of the principles of cell theory.
