You can preview or test matches for automation rules before you run them by using the automation preview option. This option allows you to see how many prospects will be matched by your automation rules without actually running them. You can access this option by clicking the Preview button while the rules are in Paused mode. You will receive an email notification when the preview is finished or you can wait on the page for it to finish in real-time. The preview will tell you how many prospects will be matched and show you a sample of them. If you adjust criteria on existing automation rules, please note that automation previews will identify only prospects who have not already had the rule’s actions applied to them.

Answer A is incorrect because running the automation rule will not only show you how many matches there are, but also apply the actions to them, which may not be what you want. Answer C is incorrect because creating a list and seeing how many prospects are affected will not give you the same results as the automation preview option, since the list criteria may not match the automation rule criteria exactly. Answer D is incorrect because there is no such option as the prospect table actions. References: Automation Rules, Preview Automation Rules
