The correct answer is D. rmdir ~/\dir.
Explanation:
rmdir is a command-line utility used to remove empty directories in Linux. The tilde (~) is a shortcut for the user's home directory.
The subdirectory is named \dir, which means it starts with a backslash. In Linux, backslashes are escape characters, and they need to be escaped to be interpreted literally. Therefore, we need to use the forward slash (/) instead of the backslash () to specify the directory name.
Option A: rmdir '~/\dir' This command will not work because the directory name is not correctly specified. It uses both the tilde and backslash, which are not interpreted correctly. Also, the quotes around the directory name are unnecessary.
Option B: rmdir "~/\dir" This command is similar to option A and suffers from the same issues.
Option C: rmdir ~/'dir' This command will not work because it is missing the backslash in the directory name.
Option D: rmdir ~/\dir This is the correct command because it uses the tilde to refer to the user's home directory, and the forward slash to specify the directory name, correctly escaping the backslash.
Option E: rmdir ~/\dir This command will also work because it escapes the backslash correctly, but it is not necessary to escape the backslash twice.
