One theory concerning the importance of vitamin C in the human diet holds that vitamin C plays a crucial role in the production and maintenance of the body’s supply of collagen, an important protein occurring almost exclusively in connective tissue and bones. For this reason, some doctors believe that vitamin C can be useful in treating the symptoms of some common illnesses.

Summary
A theory surrounding the importance of vitamin C contends that it plays a crucial role in producing the body’s supply of collagen, a protein that is almost exclusively present in connective tissue and bone. Because of this, some doctors believe that vitamin C can be useful for treating symptoms of some common illnesses.

Strongly Supported Conclusions
Some common illnesses (or their symptoms) are caused by a lack of collagen in the body.
Some common illnesses impact the health of one’s connective tissue and bones.

A
Some doctors believe that there are illnesses that affect the state of connective tissue or bones.
The stimulus says, “for this reason” (vitamin C plays a crucial role in producing collagen) some doctors think it can be useful to treat symptoms. It is reasonable to assume that these illnesses impact connective tissue and bone, where collagen is almost exclusively present.
B
Some doctors believe that vitamin C is the only substance that produces and maintains collagen.
There is no support to suggest that vitamin C exclusively produces collagen. The stimulus only specifies that collagen *almost* exclusively occurs in the body’s connective tissue and bones. But there is no link to vitamin C being the sole provider of it.
C
Some doctors believe that strengthening connective tissue and bones increases the body’s ability to use certain vitamins.
This has the logic flipped. It's reasonable to assume that some doctors believe vitamin C strengthens bones and connective tissue (not the other way around).
D
Some doctors believe that use of vitamin C is the most effective treatment for certain common illnesses.
This is too strong to support. The stimulus specifies that some doctors recommend vitamin C to treat some illnesses. But there is no evidence that it is the *most* effective treatment.
E
Some doctors believe that any illness that can be ameliorated with vitamin C causes deterioration of connective tissue and bones.
This is too strong to support and not very well supported. The stimulus only says that *some* (not any) illnesses can be helped by vitamin C. It is also a bit of an assumption to suggest that these illnesses cause deterioration in the bone.
