You can apply an action to a prospect who views a specific page of a website through a page action. A page action is a task that is performed when a prospect views a page that matches a certain URL or wildcard. You can use page actions to perform various actions on prospects, such as sending emails, adjusting scores, changing campaigns, or adding tags. You can also use page actions to track and report on the performance of specific pages on your website.

Answer A is incorrect because you cannot apply an action to a prospect who views a specific page of a website through a completion action. A completion action is a task that is performed after a prospect successfully completes a marketing element, such as a form, landing page, or custom redirect, not after they view a page. Answer B is incorrect because you cannot apply an action to a prospect who views a specific page of a website through an automation rule. An automation rule is a criteria-based action that is triggered when a prospect matches the rule, not when they view a page. Answer C is incorrect because you cannot apply an action to a prospect who views a specific page of a website through scoring. Scoring is a numerical value that indicates the level of interest or engagement of a prospect in your products or services, not a way to perform actions on prospects. Answer E is incorrect because none of the above is not a valid answer, as explained above. References: [Page Actions], [Completion Actions], [Automation Rules], Scoring
