The works of one of America’s finest 20th century artists, Edward Hopper, have been subjected to much critical discussion by art aficionados, although, significantly, not the general public who he has always been appreciated by.
I visualised it as a meaning problem, the meaning intended by author is that only art aficionados criticized his work and not the general public. Once, the meaning was clear - all the "not only, but also" ACs are eliminated, leaving us with only A, C and D.
A) by art aficionados, although, significantly, not the general public who he has always been appreciated by. - who is wrong, should be whom
B) not only by art aficionados but also, significantly, the general public by whom they have always been appreciated. - eliminated in first glance
C) by art aficionados and, significantly, not by the general public, always appreciating them. - modifier error
D) by art aficionados, although, significantly, not by the general public by whom they have always been appreciated. - no glaring errors
E) by not only art aficionados but also, significantly, the general public by whom they have always been appreciated. - eliminated in first glance
