C) The pretreatment-posttreatment cohort design
D) The reversed-treatment pretest-posttest cohort design

Posttest-Only Cohort Design

A study design in which a cohort is observed after an intervention or event, without a pretest comparison, similar to posttest-only control but typically observational.

Pretreatment-Posttreatment Cohort Design

A study design where a cohort is observed over time, with measurements taken both before and after an intervention to assess its impact.

Reversed-Treatment Pretest-Posttest Cohort Design

An experimental design where the order of treatment conditions is reversed for different cohorts, allowing assessment of treatment effects over time.

Final Answer :
B
Explanation :
The posttest-only cohort design with partitioned treatments has more than one level of treatment because different participants in the cohort receive different treatments. The other designs listed only have one level of treatment.
