Because the campaign relies on a pre-built MobileConnect Filtered List (rather than a fresh import each cycle), the correct weekly automation sequence begins with a Refresh Mobile Filtered List activity, which re-evaluates the filter criteria (birthdays falling within the current week) against the existing contact population and updates the list ' s membership accordingly for that week ' s run. Once refreshed, the Outbound Send activity is the correct Automation Studio activity to dispatch the pre-configured Outbound Message created in MobileConnect to the newly refreshed filtered list — ' Outbound Send ' being the specific, documented activity name used to trigger a MobileConnect Outbound Message, as distinct from a generic ' Send SMS ' activity name. Options C and D both reference a ' Send SMS ' activity, which is not the precise, correct Automation Studio activity name for dispatching a MobileConnect Outbound Message — this naming distinction matters for exam accuracy. Options B and D both propose ' Import Mobile Contacts, ' which is unnecessary and incorrect here, since the scenario explicitly states a Filtered List already exists and simply needs to be refreshed on each cycle, not re-imported from scratch.
