Saving and exiting a file in vim after making changes is accomplished using the command that instructs vim to write (save) the file and quit the editor. The command ":wq" stands for "write and quit." When you issue this command, vim first saves any changes made to the file, ensuring that all your edits are preserved, and then it closes the vim editor.

The other options do not fulfill the requirement of both saving changes and exiting vim. For instance, ":q!" would quit without saving any changes, which is not suitable if you want to keep the modifications you've made. The command ":x" also serves a similar purpose as ":wq," but it is less common and may behave differently under certain circumstances, such as when no changes were made. Lastly, ":v" is not a recognized command for saving or exiting and would not perform any of the intended actions. Therefore, ":wq" is the correct choice for saving and exiting vim after edits.
