What allows you to reposition or change the size of a chart on the worksheet?

Resize or move option

The correct answer is option 2- Resize or move option.

Resize or move option allows you to click and drag the chart to reposition it or use the handles around the chart to resize it directly on the worksheet.

Resizing of the chart means changing size of the chart as desired. This option can be used independently for the fonts, title, legends easily. The first step is to select the chart by clicking the left button of the mouse. Move the cursor on the corners or middle of the borders of the chart/graph which will provide the figure (the cursor will take the shape of a two headed arrow). 

OTHER OPTIONS

• Format tab – Used to change the appearance of the chart, not necessarily for moving or resizing.
• Data validation – Used for controlling what data can be entered in cells.
• Freeze panes – Keeps rows or columns visible while scrolling, not related to charts.
