The correct answer is: Valid.
Valid data is data that is in the correct format and meets the requirements of the application. For example, if an application is expecting a user to enter a number, then any number that is entered will be valid data. However, if the user enters a string of characters, then that data would be invalid.
Invalid data can cause problems for applications. For example, if an application is expecting a user to enter a number, but the user enters a string of characters, then the application may not be able to process the data correctly. This can lead to errors or even crashes.
It is important to validate data before it is processed by an application. This can be done by using a variety of techniques, such as checking the format of the data, checking the range of values, and checking for errors.
Here is a brief explanation of each option:
- Valid data is data that is in the correct format and meets the requirements of the application.
- Invalid data is data that is not in the correct format or does not meet the requirements of the application.
- Numeric data is data that is a number.
- Character data is data that is a string of characters.
