which of the following is not a valid Zoom percentage in Excel?

Explanation: The valid zoom range in Excel goes from a minimum of 10% to a maximum of 400%. This allows you to adjust the view of your spreadsheet to focus on specific details or see more of the overall data at once.

Here's a breakdown of the valid options:

A. 10: This allows you to see a very small portion of the spreadsheet with high magnification.

B. 100: This represents the default zoom level, showing the data at its actual size.

C. 300: This offers a zoomed-in view with three times the normal size, helpful for examining specific cells.

While there's no technical limitation preventing a zoom percentage beyond 400%, Excel doesn't offer options exceeding that level. It might become impractical to work with the spreadsheet at such high magnifications.
