The correct answer is:
**A. Group B; their first results are verified by others' trials.**
Group B performed all the steps three times, which means they have multiple trials of their investigation. This repetition allows Group B to verify their results, identify potential outliers, and assess the consistency and reliability of their findings. When multiple trials are conducted, it is easier to identify trends and reduce the influence of random errors, leading to more reliable results. Group A, having only performed the steps once, lacks this level of verification and reliability.
