The ______ symbol is used at the beginning of a flow chartOvalRectangleDiamondNone of these

The correct answer is Oval.

In flowcharts, the oval symbol, also known as the "Terminator" symbol, is used to represent the start and end points of a process. It indicates where a flowchart begins and ends, making it clear to the viewer the boundaries of the process being depicted. Each flowchart typically starts with a "Start" oval and ends with a "Stop" or "End" oval.

Other symbols like rectangles represent process steps, and diamonds indicate decision points within the flow of the chart. Therefore, the oval is specifically designated for the start and end of processes in flowchart representations.
