B). While at the same time introducing some 100,000 dangerous chemical pollutants that have.

Explanation:

As per the question, option B i. e. 'while at the same time introducing some 100,000 dangerous chemical pollutants that have' displays the sentence that correctly revises the underlined phrase as it appropriately employs the 'introducing' (in simple present form) which makes it correct both grammatically and syntactically. The other options are either grammatically incorrect (incorrect use of modifier in option C) or involves an incorrect cause-effect scenario (in options A and D). Therefore, option B is the correct answer.
