A BizTalk Server 2010 messaging solution processes XML messages. The solution uses a single
Business Activity Monitoring (BAM) activity and BAM tracking profile to extract content values from the message. Some of the values are bound to a receive port when the message is received. The other values are bound to a send port when the message is transmitted. At run time you find out that instead of one, two records are created in the BAM database for each processed message. One record contains only the values bound to the receive port. The second record contains only the values bound to the send port. You need to ensure that only one record is created that contains all the values for every message.

What should you do?

A.
Add a continuation and continuation ID to the tracking profile.

B.
In the tracking profile, associate a unique value from the message payload to the ActivityID field.

C.
Add a relationship to the tracking profile.

D.
Add a document reference URL to the tracking profile.
