A) a completely randomized model
B) a randomized block model
C) a two-way factor model
D) all ANOVA models
E) none of these
Experimental Design
The process of planning an experiment to ensure it can test hypotheses effectively and produce valid and reliable results.
Interaction
In statistics, it refers to situations where the effect of one variable on an outcome is modified by another variable.
- Acknowledge the value of interactions in designs utilizing ANOVA.

Final Answer :
C
Explanation :
Interaction can only be tested in a two-way factor model, where two factors are being simultaneously manipulated. In a completely randomized model, there is only one factor being tested, and in a randomized block model, the blocking variable is not a factor being manipulated. Therefore, the best choice is C - a two-way factor model.
