you're right: it's about parallelism.
you have the following:
Unlike _______, Perot's
independent run blah blah blah...
therefore, whatever is in the sentence's opener, directly following "unlike", MUST be parallel to perot's
run for presidency, NOT to perot himself.
the first 4 choices are all people. these would be parallel to perot himself, but not to his run for the presidency.
strike them all.
the last choice describes other candidates' candidacies, a notion that's logically parallel to perot's run for the presidency.

E is " the independent candidacies" parallel with" H Ross Perot's independent run for"? In my view, there are no parallellism among 5 choices.
wrong.
"independent candidacy" and "independent run" are exactly the same thing, so they're definitely parallel.
maybe you didn't know "run" could be used to mean "candidacy".
well, now you do!
