we need to support the following SI gives rise to RF.
so, if the bacteria that the SI has is similar to the cells of the body attacked in case of RF, then basically SB should give rise to RF. This is a direct strengthener and very straightforward in my opinion.
D it is. rest of the choices are out of scope
Rheumatic fever is the most serious complication of streptococcal infection, but rheumatic fever is not itself an infection. Rheumatic fever occurs only when, in defending against streptococcal infection, the body's immunological system produces antibodies that also attack the cells of the heart and kidneys.
Which of the following, if true, would contribute most to an explanation of why only streptococcal bacteria give rise to rheumatic fever?
(A) Only certain strains of streptococcal bacteria are associated with rheumatic fever.
(B) The antibodies that the body produces to control a streptococcal infection can attack cells of the mucous membranes
(C) Antibiotics have not proved as effective against streptococcal infections as they have against some other bacterial infections.
(D) Streptococcal bacteria are the only bacteria that are structurally similar to the cells of the body attacked in the rheumatic fever.
(E) Rheumatic fever can be misdiagnosed if it is not preceded by a serious streptococcal infection

option e , if anything, weakens the argument by saying that the R-fever can actually happen without the s infection being involved.

I don't think it weakens.I would say it is irrelevant
We must not forget our argument: Rheumatic fever occurs only when, in defending against streptococcal infection,
E says : If R-fever can happen due to other factors then it will be misdiagnosed. It indicates that R-fever can happen only due to S infection. This statement is repetition of what is given in argument.
It doesn't give me any information why streptococcal bacteria only give rise to rheumatic fever.
hence E is irrelevant.
