A horizontal bar chart used in project management that is commonly used to plot theplanned and actual progress of project activities is known as:

A Gantt chart is the specific and standard project management tool that fits the description. It is a type of bar chart that visually represents a project schedule over time. The vertical axis lists the tasks or activities to be performed, and the horizontal axis represents time. Each activity is shown as a horizontal bar, the length of which corresponds to the activity's duration. These charts are fundamentally designed to illustrate the start and finish dates of project elements and are commonly enhanced to track the progress of activities against the initial plan.

B. Agreement chart: This is not a standard term in project management for a schedule tracking tool. It more likely refers to a chart visualizing consensus or survey results.

C. Progression chart: This is a generic, descriptive term, not the specific name of the tool. A Gantt chart is a type of progression chart, making "Gantt chart" the more precise answer.

D. Performance chart: This is a broad category of charts that can include various tools like control charts or burndown charts. It lacks the specificity of "Gantt chart."
