You can delete a prospect through the prospect table actions. The prospect table is a list of all the prospects in your Marketing Cloud Account Engagement account, which you can access by navigating to Prospects > Prospect List. From there, you can select one or more prospects and click on the Tools button to see the available actions. One of the actions is Delete, which will permanently remove the selected prospects from your Marketing Cloud Account Engagement account. You can also delete a single prospect by clicking on their name and then clicking on the Delete button on their record.
Answer A is incorrect because you cannot delete a prospect 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. You can use completion actions to perform various actions on prospects, such as sending emails, adjusting scores, changing campaigns, or adding tags, but not deleting them. Answer B is incorrect because you cannot delete a prospect through an automation rule. An automation rule is a criteria-based action that is triggered when a prospect matches the rule. You can use automation rules to perform various actions on prospects, such as sending emails, adjusting scores, changing campaigns, or adding tags, but not deleting them. Answer C is incorrect because you can delete prospects, as explained above. References: Prospect List, [Delete Prospects], [Completion Actions], [Automation Rules]
