FederalistIMO you shouldn't select/reject a choice for such idiomatic differences. They are not usually a clear differentiator. GMAT often gives a better reason to select/reject the answers rather than such nuances.
Quote:
B. The modern jet airplane makes
it possible that
a person to travel great distances in only a few hours under conditions of great comfort and safety
IT is a placeholder and does not have a noun antecedent.
The correct usages are :
IT is xxx THAT <clause>
IT is xxx TO <verb>....if we re-write the sentence -
It makes possible THAT a person TO travel... Incorrect (That should be followed by a clause).
It makes possible THAT a person travels great distances -- Correct.
Hence B is incorrect.

Look at the meaning .
The airplane makes possible for a person
traveling great distances in only a few hours under conditions of great comfort and safety.
The greyed part is just modifying the person and can be dropped for better understanding.
So, what does airplane make possible for a person?? Incomplete in meaning.
