The correct answer is: shared.
For shared data to be useful, both the sender and the receiver need to be able to read and use the data. This means that the data needs to be in a format that both parties can understand. For example, if you are sending a spreadsheet to someone, you need to make sure that they are using the same software as you so that they can open and view the spreadsheet.
The other options are not correct because they do not require both the sender and the receiver to be able to read and use the data. For example, standardized data is data that is formatted in a way that is agreed upon by a group of people. However, this does not mean that everyone in the world will be able to read and use the data. Similarly, fixed data is data that is not changed over time. However, this does not mean that everyone in the world will be able to read and use the data. Finally, delimited data is data that is separated by special characters. However, this does not mean that everyone in the world will be able to read and use the data.
In conclusion, the correct answer is: shared. For shared data to be useful, both the sender and the receiver need to be able to read and use the data.
