In an A-B-A single case experimental design, the "B" refers to the period during which the treatment (or intervention) is being applied. The "A" refers to the baseline period before the treatment is applied, and the second "A" refers to a return to baseline after the treatment is removed. Thus, the correct answer is B. Choice A is incorrect because the "A" refers to the period before the treatment is applied, not when it is not being applied. Choice C is incorrect because the dependent variable is assessed throughout the entire experiment. Choice D is incorrect because only choice A is incorrect.
