A conversion optimization specialist wants to run a test on a Campaign's hero image. The goal is to test three new images (Treatment A, B, and C) against the original version to see which one generates the most clicks. A small portion of the audience should be reserved as a baseline.
What is the correct way to configure this content experiment?
A. Two treatments (A, B) and a control group, which will automatically receive a third version.
B. Three treatments (A, B, C) and a hold-out group, with the audience split between all four.
C. One experiment for A vs. the original, and a second experiment for B vs.
D. Three treatments (A, B, C) with the audience split evenly between them.
