Quizplus · Accepted Answer

Only option D describes a true experimental design, as it involves testing two conditions within subjects (meaning each participant experiences both conditions and serves as their own control). Options A and B lack control groups, which are important for comparison purposes, while option C lacks a control group and pre-testing, which is important for establishing a baseline and controlling for initial differences between groups.
