I spend 5 sec to think between B/ E
Is E incorrect because ORIGINATED and FLOURISHED
can not occur at same time (as suggested by simple past tense) ?
We need HAS FLOURISHED since first the virus originated and later
flourished (the effect of flourishing) is still present in current time.
Hence B should be correct.
Is my approach correct?

The right answer to this question is B. The main concept being tested here is tenses, and the understanding of when we're talking about the aforementioned actions. The main actions we have to look out for are "originating" and "flourishing".
Options A&C - "has originated" is incorrect. The use of present perfect here does not work because the act of originating is a single act that happened in the past. The present perfect is used for actions that may have started in the past but are still in progress at the current reference point in the present. Hence, we can eliminate both these options. OUT
Option D - "had flourished" is incorrect. One should only use the past perfect if the action both happened in the past and stopped by the time another reference point in the past rolled around. In fact, a rule of thumb would be to never use the past perfect unless there is a later past action indicated as well. OUT
Option E - "flourished" is close. However, we want to say that the virus is still flourishing, it has been and continues to. Using the simple past indicates that this was a single action in the past, thereby altering the meaning of the sentence. OUT
Option B - gets both "originated" and "has flourished" correct, and since the others don't, is the right answer!
Always remember in SC that there is no perfect way to construct a sentence. The right answer is correct simply because the other ones are clearly wrong.
