B is my answer.

A uses which, which is a non essential modifier and is not preceded by a comma. Almost all the time which is preceded by a comma.

Also the word perpetuated is past tense and originated is the correct form on the other side.

ing in E can be ignored for obvious reasons

What is the OA?
