AS we are contrasting AMATEUR ATHLETES ...VS PROFESSIONAL ATHLETES.
so in order to make the structure parallel....we need PROFESSIONAL ATHLETE just after comma
only C and D PROVIDE so..

C) professional athletes, by measuring their performance with sophisticated diagnostic equipment, are better able to focus their efforts and improve
correct.

D) professional athletes, by measuring their performance with sophisticated diagnostic equipment, are better able to focus their efforts and improved

highlited part is not parallel.
are better able
to focus their efforts
and
{to} improved their skills quickly

we need improve to make parallel.

hence C

waiting OA.

Between C and D as we need Professional Athletes after comma - ABE are out.

Between C and D - C should be right option as "able to .....improve" makes sense rather than "improved".

Options A, B and E are out since the contrast/comparisoon is incorrectly made between amateur athletes and 'measuring....'
Leaves us with C & D.
D does not follow the correct verb tone of the sentence i.e the correct part fo the sentence says.."...amateur athletes who improve..." and in D it says..."....their efforts and improved'

Leaves us with C which In IMO is the correct answer.
