An A-B-A-B design involves an initial baseline measurement (A), an intervention phase (B), a return to baseline (A), and a second intervention phase (B). Option D accurately describes this sequence by assessing anxiety, introducing an intervention (video clips of baby animals), removing the intervention, and then reintroducing the intervention, with assessments at each phase.
