Regarding the separation of read and write of the database, it is assumed that the workload of a database is 20% write and 80% read, with the following premise: 1) Read and write queries consume the same resources. 2) All servers have the same configuration. 3) All read operations can be transferred to the slave library. So if a server can support 1000 queries per second, how many slaves will be added to increase the load to 2000?
A, 1
B, 2
C, 3
D, 4
