Since the President was caught having an affair, nearly 10000 men have been sued for divorce, which is more than had been sued in the past five years combined.

(A) which is more than had been sued
(B) more than had been sued
(C) more than they had sued
(D) more than had experienced suits
(E) which is more than had experienced suits

please underline the necessary portion of the sentence.

which refers to divorce instead of action in which 10000 men get sued. so A and E are incorrect.
C is confusing in meaning since it means that 10k men have been sued for divorce and this figure is more than these 10k sued others.
use if they adds improper meaning to the sentence.
D is awkward since experienced suits is passive and experience of getting sued is meaning less.

the sentence means that
more than the divorce cases filed in past five years combined, these 10k divorce cases is large in number.
past perfect also fits to the bill according to the scenario.

It was a battle between A and B.

Since the President was caught having an affair, nearly 10000 men have been
sued for divorce, which is more than had been sued in the past five years combined.
(A) which is more than had been sued
(B) more than had been sued

I chose A even though it seemed wrong and it was clearly wrong as relative pronoun "which" shouldn't be modifying "divorce".
But B also has a problem that "no clause after than", since we are comparing divorces before and after president was caught. Can you please shed some light in this matter. Any help would be appreciated.
