Final Answer :
A
Explanation :
The serious flaw associated with the nonequivalent control group design is that selection differences can occur. This means that the groups being compared may differ in ways that affect the outcome, which cannot be attributed to the intervention being studied. In other words, it is possible that any observed differences between the groups are due to factors other than the treatment, making it difficult to draw valid conclusions about its effectiveness.
