Answer 1

Answer:

B. To restrict the type of data that can be entered into a cell

Excel offers various criteria for data validation:

• Whole Numbers: Allows only integer values within a specified range (e.g., between 1 and 100).

• Decimal Numbers: Permits decimal values within a defined range.

• List: Restricts entry to a predefined list of items. This is often used for dropdown menus, ensuring users select from approved options.

• Date: Validates that the entered data is a date and falls within a specified range (e.g., after 01/01/2023).

• Time: Ensures that the entered data is a valid time and falls within a specified range.

• Text Length: Limits the number of characters that can be entered (e.g., exactly 10 characters for a phone number).

• Custom (Formula-based): Allows users to create complex validation rules using Excel formulas.
