The answer is D, carbon dioxide, because carbon dioxide is used in photosynthesis. The answer is not b, glucose, because the end product of photosynthesis is glucose.

Acid rain is simply rainfall that has been rendered acidic due to water vapor reacting with nitrogen oxide ad sulphur dioxide very high up in the atmosphere.
Acid rain is not only a threat to the ecosystem and environment, but also seriously damages buildings and sculptures.
Marble and limestone are especially vulnerable to acid rain. This is because the two building or construction materials contain calcite which is easily dissolved by acid.
Concrete surfaces and paint finishes are also seriously damaged by acid rain.
CONTRACTILE RINGS are a contractile ring of actin micro filaments that eventually results in the division of the cytoplasm.
The contractile ring are usually formed during the early anaphase phase of the cell division cycle. During the cellular cleavage, the contractile rings tighten around the cytoplasm of the cell until it is pinched into two daughter cells.
Based on that scenario, a faulty reasoning that the student's research advisor most likely point out is : The rock that makes up the fossils replaced the organisms tissue and genetic material,
Because of this , their genomes can't be extracted.
hope this helps
