Ans: B
Exp : When you specify consistency level as ALL then it will make sure that the read request checks all copies and takes the latest or for write acknowledgement of successful write is only returned when all the copies have been updated. If program is writing heavy, specify Write ONE and Read All and if program is read heavy specify Read ONE and Write ALL.
