The correct response is:
**Group B; their first results are verified by other trials.**
This is because Group B repeated the experiment three times, which allows for the verification and averaging of results. Repeating trials helps to identify any outliers and provides a more reliable data set due to increased sample size and the ability to mitigate random errors.
