IMO C

I would go with C.

Because of the ;, we need an independent clause after the ;, so A,E Eliminated.
B is changing the meaning and D is wrong in construction.

since there is a semi-colon we need an independent statement that can stand on its own.

Hence we can remove A and E.

D is wrong coz it doesnt fit well .

Im confused b/w B and C

can you please provide OA and OEs

thanks

(A) "Arguably...., " is the phrase that should describe the subject on the other side of the comma. Instead, we have "and has become..."--which does not make sense in A.

(B) it's quite wordy "and, as a result of this..." Eliminate it.

(C), "arguably" describes the word next to the comma "it"-- Correct

(D), you don't need the comma before "and"----if you use a comma, then there needs to be a subject on the right side of the comma

(E), where's the subject? It starts with "is"--which does not make sense. Remember the underlined portion should read as a complete sentence so it cannot start with "is . Incorrect.
