A Control chart is specifically designed for tracking the performance of a process over time by plotting data points on a graph at regular intervals. This enables quality control professionals to monitor the stability of a process and identify any trends or patterns that may indicate changes in performance. A Pareto diagram is used for identifying the most common sources of defects or quality issues, a histogram is used for showing the distribution of a set of data, an Ishikawa diagram is used for identifying the potential causes of a problem, and a cause-and-effect diagram is used for tracking the relationships between different factors that influence a process. Therefore, A is the best choice for the given description.
