Viruses can have beneficial effects. For example, some kill more complex microorganisms, some of which are deadly to humans. But viruses have such simple structures that replacing just a few of a beneficial virus’s several million atoms can make it deadly to humans. Clearly, since alterations of greater complexity than this are commonly produce by random mutations, any virus could easily become dangerous to humans.
If the statements above are true, then each of the following statements could also be true EXCEPT:
(A) Random mutation makes some deadly viruses beneficial to humans.
(B) Some organisms of greater complexity than viruses are no more likely than viruses to undergo significant alterations through random mutation.
(C) Some microorganisms that are more complex than viruses are beneficial to humans.
(D) Some viruses that fail to kill other viruses that are deadly to humans are nevertheless beneficial to humans.
(E) No virus that is deadly to organisms of greater complexity than itself is beneficial to humans.
If the statements above are true, then each of the following statements could also be true EXCEPT:
(A) Random mutation makes some deadly viruses beneficial to humans.
(B) Some organisms of greater complexity than viruses are no more likely than viruses to undergo significant alterations through random mutation.
(C) Some microorganisms that are more complex than viruses are beneficial to humans.
(D) Some viruses that fail to kill other viruses that are deadly to humans are nevertheless beneficial to humans.
(E) No virus that is deadly to organisms of greater complexity than itself is beneficial to humans.

The para is NOT extreme, that is, it nowhere speaks of terms such as ALL or NONE, and this question is about COULD be true, so in all probability our answer should be something extreme, because otherwise almost everything could be true

(E) No virus that is deadly to organisms of greater complexity than itself is beneficial to humans.
If you look at the choices, A to D are using term SOME, so they are NOT extreme.... A to D, therefore, can be true.
E talks of NO virus, so too extreme to fall into ' could be true'..

In addition to explanation above by chetan2u answer will be e because-
We do not know for a fact that there are some viruses that are not deadly. We are told that some are deadly. This could mean anywhere from 1 virus to all viruses. We do not know that there are viruses that are not deadly from the stimulus.
We do necessarily know that some viruses that are deadly are beneficial to humans.
We know that some viruses are deadly to more-complex microorganisms. Some of these more-complex microorganisms are deadly to humans.
So we do have a case of some deadly viruses that are beneficial to humans. These viruses are killing things that are deadly to humans
