The correct answer is: C. Gantt chart.
A Gantt chart is a type of bar chart that illustrates a project schedule. The horizontal axis of a Gantt chart shows the time period, and the vertical axis shows the tasks or activities to be completed. The length of each bar represents the duration of the task, and the start and finish dates of each task are shown by the intersection of the bar with the time axis.
Gantt charts are a popular tool for project management because they provide a clear and concise way to visualize the schedule of a project. They can also be used to track progress and identify potential problems.
The other options are incorrect because they are not types of charts. A cent chart is a type of currency chart, a gault chart is not a real type of chart, and a grand chart is a type of bar chart that is used to show the distribution of data.
