Non-equivalent-groups and time-series designs are two specific types of quasi-experiments. Experiments are a distinct type of design and quasi-experiments are used when true experimental designs cannot be used for practical or ethical reasons. The statement that all research purposes are amenable to experimental designs is false, as some research questions cannot be ethically or practically studied using experimental designs. Therefore, option D is false.
