Remove choice A for saying 'with whom they shared". 'They' is absurd

Remove C also for saying 'both men' shared

Remove E for using the expression -- Dirac shares in 1933--

In D 'towards' and 'to' are not parallel.

To and to is better as in B

Hi Daagh,

If in E expression is - Dirac shared in 1993 - then which option will be preferred B or E..

Between B and E, I would still prefer B, since the diction 'essential to' and 'to his efforts' are more focused and sharper than 'essential in' and 'in his efforts'

A to his productive collaboration with Edwin Schrodinger, with whom they shared a Nobel prize in 1933, and to
Use of THEY is incorrect since such use means that there was someone else, apart from Paul and Edwin, who shared a Nobel Prize, an idea contrary to original intent that Paul shared Nobel prize with Edwin.
B to his productive collaboration with Edwin Schrodinger, with whom Dirac shared a Nobel prize in 1933, and to
Correct
C to his productive collaboration with Edwin Schrodinger, with whom both men shared a Nobel prize in 1933, and to
Use of BOTH is incorrect on the lines as explained in option A.
D towards his productive collaboration with Edwin Schrodinger, with whom Dirac shared a Nobel prize in 1933, and to
ESSENTIAL TO is correct use.
E in his productive collaboration with Edwin Schrodinger, with whom Dirac shares a Nobel prize in 1933, and in
ESSENTIAL TO is correct use.

Can any one please explain me how to eliminate (E) In the context of the sentence. how does pronoun in / to fits better and why?

"Essential TO" is the correct Idiom - "essential IN" is wrong.

You have to memorise the idioms, there are no rules for them.
