The best choice is to use the x-bar chart because it is used to monitor the central tendency (mean) of a process. Since the OM team wants to monitor the central tendency of the production process, an x-bar chart is appropriate. To determine if the process is in control, the team would need to analyze the control limits and evaluate if any points fall outside of those limits. If all the points fall within the control limits, the process is considered to be in control.
