Identifying the modifier and the modified entity would pretty much solve the question here.

"Once portrayed as xyz" is the modifier, whereas, in Option A, this modifier is modifying "the advancement of AI technologies". But the advancement was never portrayed as xyz, right - the AI technologies were. This error eliminates options A, C, and E.

Between B and D, the contrast is only reflected in B. So imo, B is the right answer.

Modifier should be AI, not rapid advancement of AI, so E is wrong.

B is the only one that has a proper sentence structure with correct modifier placement.

option E is the right answer in my view. It rightly places 'to' before revised definitions and makes the statement logically as well as grammatically correct.
