Setting up a corporation requires more paperwork and legal provision

lets draw an analogy :

Keeping aside all grammar : what will u put in the blank, taking cues from one's daily usage and sheer logic

Getting a 50 in Verbal requires more hardwork THAN...........................

A : To get a 50 in Quant
B : What it takes to get a 50 in Quant
C : To get a 50 in Quant
D : Getting a 50 in Quant
E : Getting a 50 in Quant

Guess B is an outwright NO ; AC AND DE are close contenders

Bxn AC & DE :

AC : Getting a 50........... THAN........To get a 50 : Parallelism broken

DE : Getting a 50.............THAN.........Getting a 50 : Parallelism Intact

Thus DE Wins , Now bxn D & E ( lets get back to the original Q )

The intent : Doing A requires more work than doing B or doing C and not that doing A requires more work than doing B and C

E : Setting up a Corp............THAN.........Establishing X and Y == Eliminated

D : Setting up a Corp.............THAN........Establishing either X or Y ==Perfect

Leading to D , my take.
