Final answer:
Without additional context, it is not possible to determine which option correctly answers the question about the number of members in the largest group of team offenders identified.
Step-by-step explanation:
Looking at the information provided, we do not have enough context to definitively answer how many members were in the largest group of team offenders identified, as the options a) two, b) nine, c) five, d) four, seem unrelated to the provided reference statements.
However, if we interpret 'team offenders' within the second reference context regarding the number of people enslaved, option b) nine might be referencing the largest group that enslaved between one and nine people each, based on what's given in part B.
