Weathering (erosion), transportation, deposition, compaction. Essentially D is the correct answer.
Maybe if you insert a picture, we can help you.
Answer: The bacteria uses the oxygen present in the mouth.
Explanation:
The plaque that is formed in the teeth is a highly anaerobic bacteria but it can sustain in the environment rich in oxygen. The oxygen is used by the bacteria and there is a absence of oxygen in the teeth.
It is formed in between the teeth which needs oxygen to survive and if remains for tooth for a longer period of time then it began to grow without oxygen.
It basically uses the oxygen available in the mouth and makes the condition anaerobic.
Kidney would be the best answer here.

You are familiar with the electron transport system in photosynthesis
that takes light energy and converts it to chemical bond energy in the
form of ATP and NADPH. This electron transport chain in cellular
respiration will take the energy stored in NADH and FADH2
during the Krebs cycle and convert it to chemical bond energy in the
form of ATP. In eukaryotes, this reaction takes place on the inner
mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that
undergo aerobic respiration also have an electron transport chain
located within their plasma membrane, which may be highly folded similar
to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps
