Which of the following could cause data to appear improperly formatted?

The notion of improper formatting of data can be significantly influenced by the way text is organized and structured, particularly when it comes to line endings. Different operating systems utilize various characters to signify the end of a line. For example, Windows typically uses a carriage return followed by a line feed (CRLF), while Unix-based systems use just a line feed (LF). If data is created or stored in one format but then read or processed in another, it can lead to improperly formatted output, with lines running together or displaying unexpected behavior.

This misalignment in line endings can cause applications to misinterpret where one line ends and another begins, leading to a jumble of data that's difficult to understand or analyze. Hence, ensuring that the right line endings are utilized according to the specific environment or application is crucial for maintaining proper formatting of data.
