Correct is A (manager)
https://docs.oracle.com/goldengate/1212/gg-winux/GWURF/gg_parameters122.htm
PURGEOLDEXTRACTS should only be used in an Extract or Replicat parameter file if there is only one instance of the process. If multiple groups are reading the same set of trail files, one process could purge a file before another is finished with it. Instead, use the Manager version of PURGEOLDEXTRACTS, which is the preferred use of the parameter in all Oracle GoldenGate configurations because it allows you to manage trail files in a centralized fashion.
Correct answer is A, because there are mutltiple gg processes are running and accessing the trails. If single process, then you can use extract or replicate parameter file.
