Please someone help me with this. I am not able to proceed here.

Hi Blue_Skies,

IMO E


With some is preferred over some. Hence eliminate A and D.

Among B, C and E, E is the most concise of all and is also parallel.

B and C have 'others did not' in them. The 'did' makes them a bit awkward. E omits that and hence is the best of all.
