What is a possible root cause of the spike in IOPS?

A storage administrator performs a monthly performance analysis of a Dell EMC Unity XT storage array using CloudIQ insight reports. Three LUNs are set with a Host IO Limits policy. The administrator discovers that the throughput IOPS on one LUN (Test_LUN) has increased by 1000 IOPS compared to the two previous months.

What is a possible root cause of the spike in IOPS?
A . Test_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set for all three LUNs
B . Test_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set only for Test_LUN
C . Host IO limit of Test_LUN was edited and the limit was increased by 1000 IOPS
D . Another Absolute Host IO limit policy with additional 1000 IOPS was set on Test_LUN
