Answer:
a. internal
Explanation:
This experiment results show that the drug effect on patients was effective improving their immune functioning so external validation would be sufficient for this study.
Statistical information shows that the difference between the treatment group and the control group wasn't significant but still shows the improvement on immune system and effectiveness in Jeremy's test.
The drug improved the participants immune functioning as it claimed it would so costruct validation would be sufficient.
We cannot be sure that the drug stablishes a trustworthy cause and effect relation between treatment and outcome on patients and alternative explanations can be found since there was an improvement on the control group immune system as well.
Internal validation requires a trustworthy cause and effect relationship between treatment and outcome stablished by the experiment so it isn't sufficient for this study.
