The marketing team wants a new picklist value added to the Campaign Member Status field for the upsell promotional campaign. Which two solutions should the administrator use to modify the picklist…

The "Campaign Status" field is a standard picklist on the Campaign object for the overall campaign status, not the Campaign Member Status, and modifying it in Object Manager would change the standard values, not the member-specific ones.

Campaign Member Statuses are managed directly on the Campaign record via the 'Campaign Member Statuses' related list, allowing an administrator to add, edit, or delete values specific to that campaign. This is the correct interface for managing these picklist values.

For an administrator or user to access and modify Campaign Member Statuses directly from a Campaign record, the 'Campaign Member Statuses' related list must be visible and accessible on the Campaign object's page layout. Adding this related list to the page layout provides the interface for managing these values.

"Mass modify" is not a standard Salesforce feature for managing picklist values on a related list; modifications are done individually or through import tools, but not directly via a "mass modify" action on the related list itself.
