Without going into the debate of whether this is a great example or not - I personally not loving it but I think it was written to illustrate/test a grammar rule so that's what we got. I would say 2 things:
1. Passive voice can be OK but it has to pass a higher standard of error. Meaning that the error in the active voice statement has to be meaningful. Otherwise slight ambiguity + active will win over passive.
2. In this case, while you could argue that there is ambiguity by looking at "they", if you expand your vision, you will see that the statement says "they can correct these fundamentals" addresses 95% of the ambiguity since "they" can only really refer to athletes in that statement.

I understand that in most occasions active voice is preferable than passive voice, but in the question, I would prefer E over A. As E avoid any pronoun ambiguity.
IMO, the "they" in A may refer back to athletes or poor fundamentals. Therefore, after weighting the preference between the active/passive style and pronoun ambiguity, I believe E is more preferable.
