Ans : C

Exp : Lets understand the basics of the listed command

• tablestats: Provide statistics about one or more tables. Statistics are updated after SSTables changes through compaction or flushing.

• tablehistograms : It provides the current performance statistics for read and write latency on a table during the last fifteen minutes, which includes the read/write latency, partition size, cell count, and number of SSTables. Even using this command we can analyze performance and tune individual table and ensure that the percent latency level meets the SLA for the data stored in the table.
