The Internet may not _________ everything we do, but it has already revolutionized business and will continue to do so.

'Change' is correct because it indicates transformation or alteration, which fits the context of the Internet revolutionizing business. 'Prove' doesn't make sense contextually, 'help' is too weak, 'mark' doesn't convey transformation, and 'stop' contradicts the meaning. The Internet has already fundamentally altered how business operates.
