Which fossil fuel forms in the hottest and deepest parts of the earth

Coal

Explanation:

Coal was formed hundreds of millions of years ago when prehistoric plant life died and sank to the bottom of swamps and was covered by layers and layers of sediment and rock. The increased pressure and heat of the remains, turned into coal.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

i think the answer is b.
