-Not at all. B Form normally is used for the people to provide the document for immigrant visa application outside US, not for the people to file I-485 within US in most cases though sometimes it also can be used for I-485 filing. So, you need to check this website for the I-485 filing date:

如果我的PD在2014年11月之前,我是否能這個月提交485?謝謝!
-No. I-485 filing is based on A Form in Feb, 2018, not B Form.
