Selected Answer: D
The purpose of the Bash built-in `export` command is: D. It sets up environment variables for applications. The `export` command is used to make environment variables available to child processes or subshells, ensuring that those variables are inherited by any command or application run in that context. This is essential for passing configuration and data between different processes and for setting up environment variables that applications rely on.
