OA after few explanations
Is it A?
"Research ... has revealed" is required. So, B, D and E are out.
In C, "nature of language and processes by which it" -- it lacks a clear
referrent.
Same is the problem with A; 'it' has no clear refferent. C it is
(A) that produce and make it understandable has revealed great complexity instead of underlying simplicity
'it' has no reference
(B) of producing and understanding it have revealed not underlying simplicity but great complexity
research is a singular subject, therefore 'have' is wrong
(C) by which it is produced and understood has revealed not underlying simplicity but great complexity
'...not....but...' is the right idiom, best answer
