(A) few people are known to recover from the disease after the appearance of the clinical symptoms
(B) few people are known to have recovered from the disease once the clinical symptoms have appeared

The FEAR of rabies is WELL FOUNDED. The 2nd indepdent clause after semicolon should show how THE FEAR IS WELL FOUNDED. This is possible if we say that many people have died (ALREADY DIED) over the years because of Rabies.

A says ARE KNOWN (present tense implies today) to recover (today) - we know many people recover from this disease today, but this is not conformig why THE FEAR IS WELL FOUNDED.

B - use of TO HAVE RECOVERED (past phenomenon) suggests "we know that many people have died in past of rabies". This connects 2nd clause with the first.

IMO B

I have seen that you have posted a few questions in the community during last some days.
Please do not reveal the answer of the question in the title or in the first post

Use spoiler to ask something regarding an option or to tell the answer.
Example:

OA - A




Please follow this religiously!

so going with the OA or the other convincing option??

I would request an expert to comment on this

what is the official answer

A cannot be the OA.

In the original one : The fear of rabies is well founded; few people are known to recover from the disease after the appearance of the clinical symptoms.

use of "after" is incorrect - it signifies time. Where as in B - "once..." signifies an adverb of condition. And it is more a proper representation of meaning here.

the time sequence problem is well explained by Patanjali.purpose.

the answer must me B.

Hope this helps !!
