How should the Business Practitioner modify the workflow diagram?

The entire list of recipients for a campaign is unavailable at the start of an A/B test. The final list of the

recipients will be placed in the final Recipients folder but they will be loaded by the time the A/B test is

complete. To start the A/B test, a list of exclusive recipients is used for the initial deliveries in the folder

test Recipients.

How should the Business Practitioner modify the workflow diagram?
A . modify the existing query to query all recipients in folders ‘testRecipients’ and ‘finalRecipients’
B . modify the original query to all recipients in ‘testRecipients’ and modify the split activity to query the folder ‘finalRecipients’ in the complement
C . add the enrichment after the wait toadd all recipients in the ‘finalRecipients’ folder to the complement from the split activity
D . modify the original query to all recipients in ‘testRecipients’: change the A & B branches to 50% each, and add a new query after the wait to get all recipientsin the ‘finalRecipients’ folder

Answer: B
