I pick D.
A,B out. (parallelism)
C,E means (as much as I understand) 'no humans have any natural defence against it', which I think is not the intended meaning.

D is the best.

D,E - out 'them' doesn't refer back to 'a microbe'

A,B,C

B - 'with no' - changes the meaning - out
A,C - tough one to choose

Going with A

C - 'kill' doesn't sound right in this sentense.

Stuck between A and C , I would go for C.

A ==> a microbe that might escape and it would kill (does not sound good)
C ==> a microbe that might escape and kill

Chose A.
In C:
scientists might inadvertently create an “Andromeda strain,” ...and kill vast vast numbers of ....
doesn't sounds right. It's not scientists who are going to kill but microbe..
