Option C is a multi-level treatment because the employees receive different bonus levels based on their years of service, making it a treatment with multiple levels or categories. Option A is a binary treatment where the subjects either receive the drug or placebo. Option B is also a binary treatment where the subjects are exposed or not exposed to the advertisement. Therefore, options A and B are not multi-level treatments.
