Final Answer:
To AutoFill contents, click in the bottom-right corner of a cell and drag. Option D is the answer.
Step-by-step explanation:
AutoFill is a feature in spreadsheet software that allows users to quickly fill cells with a series or pattern of data. To use AutoFill, you click and drag the small square located in the bottom-right corner of the active cell. This square is called the AutoFill handle. By clicking on this handle and dragging it in the desired direction, you can fill adjacent cells with a continuation of the pattern or series present in the initial cell.
For example, if the initial cell contains a date, dragging the AutoFill handle can automatically fill subsequent cells with a sequence of dates. This feature is a time-saving tool for efficiently populating cells with repetitive or sequential data.
Option D is the answer.
