What is required to execute one control group and two content treatments for a campaign?

The correct answer involves creating a campaign with two treatment plans and one holdout group, which effectively allows for the comparison of the two variants against a control group.

In this context, the control group serves as the baseline, enabling you to determine how the two treatments perform in relation to it. By having two treatment plans, you can test variations of your content to identify which resonates better with your target audience, while the holdout group allows you to maintain a segment that doesn't receive any modification, ensuring that any effects observed can be attributed directly to the treatments in question.

The other options lack the necessary structure or do not fully encompass the requirements for the scenario. Designating a control group and assigning two variants might seem close, but without the explicit mention of a campaign structure with treatment plans, it doesn't adequately address the need for a comprehensive approach. Collecting data from previous campaigns is valuable for insights but does not directly help in executing the current campaign's design. Utilizing A/B testing for control scenarios could apply but doesn't specifically outline the requirement of having both treatments and the control group effectively organized in a
