What is true about this situation?

A policy-managed RAC database that hosts the ACCOUNTS service has only three instances
running rather than the usual four on a six-node cluster.
Five of the six cluster nodes are active and the sixth (RACNODE6) is down for maintenance.
You decide to check the state of the servers in the server pools to see if there are problems with
the OLTP pool to which the ACCOUNTS service has been assigned.
You used the ctsctl status server -f command and see that the RACNODE3 node has
STATE=VISIBLE.
What is true about this situation?

A.
The Cluster Synchronization Services Daemon (CSSD) is running RACNODE3 is considered to
be part of the cluster, but the Cluster Ready Services Daemon (CRSD) is currently not running.

B.
Both the Cluster Ready Services Daemon (CRSD) and the Cluster Synchronization Services
Daemon (CSSD) are running on RACNODE3, but RACNODE3 is currently being moved to
another server pool.

C.
The Cluster Ready Services Daemon (CRSD) is running and RACNODE3 is considered to be
part of the cluster, but the Cluster Synchronization Services Daemon (CSSD) is currently not
running.

D.
Neither the Cluster Ready Services Daemon (CRSD) nor the Cluster Synchronization Services
Daemon (CSSD) is running on RACNODE3.
