The p chart is used to monitor the proportion of items in a sample that possess a certain characteristic. In this case, the characteristic is delivering papers on time. The purpose of constructing the p chart is to see whether the percentage of papers delivered on time is too erratic. The p chart helps determine whether a process is in-control or out-of-control. Therefore, the best characterization of the p chart is "In-control" (Option C). None of the other options are relevant to the p chart in this scenario.
