                                    A: Before the insert query, Ro needs to execute a replicate-all command using cqlsh for the session, so that the data can be replicated on 3 nodes. 
            B: After the insert query, Ro needs to execute a replicate-all command using cqlsh, so that the data can be replicated on 3 nodes. 
            C: Ro does not need to do anything, replication is taken care of by Cassandra.
