Thomas Eakins' powerful style and his choices of subject - the discipline of sport, the strains of individual in tension with society or even with themselves - was as disturbing to his own time as it is compelling for ours
A) was as disturbing to his own time as it is
B) were as disturbing to his own time as they are
C) has been as disturbing to his own time as they are
D) has been as disturbing in his own time as it was
E) have been as disturbing in his own time as
The OA is B. Seeing the problem in all other choices, I can figure out that it should be B. But my question is - in choice B the idiom as X As Y is not in parallel i.e. as disturbing(participle) as they (pronoun)
Is choice B correct gramatically?
Thanks,
