Sentence Correction

Studies on thoroughbred racing displayed that if show-horses rest adequately between competitions and raced on synthetic surfaces, they will be less likely to sustain an injury or illness than do those exhausted from rigorous training schedules.

A1) raced on synthetic surfaces, they will be less likely to sustain an injury or illness than do
R)raced on synthetic surfaces, they are less likely to sustain an injury or illness than
C)race on synthetic surfaces, they sustained fewer injuries or illnesses than do
D)race on synthetic surfaces, they have been less likely to sustain an injury or illness than do
E)race on synthetic surfaces, they are less likely to sustain an injury or illness than

OA is E
What makes Option E the best fit for this sentence, I really want a deep explanation from an Expert.

We can solve this one based on tense alone. We see that in the non-underlined portion of the sentence, we have simple present tense verb "rest". This means that the verbs in the underlined portion should also be simple present. So we can eliminate A, B, and C for past tense "raced" and A, C, and D for present perfect "have sustained". This leaves us with E.

We could also eliminate A, C, and D for parallelism issues: the verb "do" at the end of the underlined portion doesn't have a match in the thing it is being compared to.
