To determine whether the process distribution standard deviation has changed, we use the S chart. The S chart is used to monitor the process variation and identify any changes in the process standard deviation. The 11ea78b9_2e5e_f829_8379_5167e9c0ce0d_TB4388_11 chart is used to monitor the process average, and the p chart is used for monitoring the proportion of non-conforming units. Therefore, option A and C are not correct choices for this scenario.
