To test different subject line voices with a pilot group and then send the winning subject line to the remaining customers, the marketing manager should: • B. Configure a Holdback group to be targeted by the winner. By configuring a Holdback group in Path Optimizer, you can initially send the different subject lines to a smaller pilot group. Once the winning subject line is determined, the Holdback group (the remaining customers) can then be targeted with the winning subject line. This approach ensures that the majority of the audience receives the most effective subject line based on the test results.

I think " B" is the correct answer & here is the reason for it - ref (https://help.salesforce.com/s/articleView?id=sf.mc_jb_path_optimizer_test_activity.htm&type=5) QUOTE The Holdback feature is only available when you use the Run Once entry schedule type. Change the entry schedule type back to Run Once to activate the journey with a Holdback. If you want to use the Recurring schedule type, you must first change the entry schedule type back to Run Once, then remove the Holdback feature from Path Optimizer before activating your journey.

A still the best answer?

A. Place a Random Split before Path Optimizer for the pilot group. This option would allow for a specified percentage of the total audience to go through the Path Optimizer, which would test different subject lines on this subset (pilot group). The rest of the audience would not receive anything at this stage. This approach aligns with the requirement of first testing with a pilot group.

A is true
