You need to reduce the occurrence of these timeout errors

You administer several Microsoft SQL Server 2012 database servers. Merge replication has been
configured for an application that is distributed across offices throughout a wide area network
(WAN). Many of the tables involved in replication use the XML and varchar (max) data types.
Occasionally, merge replication fails due to timeout errors. You need to reduce the occurrence of
these timeout errors. What should you do?

A.
Set the Merge agent on the problem subscribers to use the slow link agent profile.

B.
Create a snapshot publication, and reconfigure the problem subscribers to use the snapshot
publication.

C.
Change the Merge agent on the problem subscribers to run continuously.

D.
Set the Remote Connection Timeout on the Publisher to 0.
