Veritas Prep Official Explanation:

The initial sentence commits a Pronoun error, using the plural pronoun 'they' to refer to the singular 'Dirac'. Similarly, choice C uses the phrase "both men" to refer to Dirac; there are only two men, and so it is illogical for 'both men' to share a prize with Schrodinger. Accordingly, A and C are both incorrect. Choice D commits a parallel structure error, using 'towards' in place of 'to'; because the sentence requires parallel construction between the two parallel elements ('to his collaboration' and 'to his own successful efforts'), the correct answer must have "to" as the connector for both elements. Choice E commits a Tense error, using 'shares' to refer to an event that clearly took place in the past tense ('in 1933).

The mathematical insights made by Paul Dirac were essential  to his productive collaboration with Edwin Schrodinger, with whom they shared a Nobel prize in 1933, and to  his own successful efforts to apply the special theory of relativity to the quantum mechanics of the electron.

A. to his productive collaboration with Edwin Schrodinger, with whom they shared a Nobel prize in 1933, and to 
they refers to both D... and Ed...
it is illogical, as D only shared with Ed
A is out

B. to his productive collaboration with Edwin Schrodinger, with whom Dirac shared a Nobel prize in 1933, and to 
to his ..., and to his ...
Parallelism is maintained, hold on to B

C. to his productive collaboration with Edwin Schrodinger, with whom both men shared a Nobel prize in 1933, and to 
Same as A. 
C is out

D. towards his productive collaboration with Edwin Schrodinger, with whom Dirac shared a Nobel prize in 1933, and to 
towards his..., and to his...
Not a parallel structure
D is out

E. in his productive collaboration with Edwin Schrodinger, with whom Dirac shares a Nobel prize in 1933, and in 
to+v shows motive. B can be preferred over E. 
There is no as such grammatical mistake in E, just B is better.

B is answer.
