Which command is used to change the current working directory?

• A. cd
• B. chdir
• C. pwd
• D. mv

Answer: (A)

The command used to change the current working directory is `cd`. This command stands for "change directory," and it allows users to navigate the file system by specifying the target directory they want to move into. For example, using `cd /home/user/Documents` would change the current directory to the Documents folder within the user's home directory. In contrast, the other commands serve different purposes. The `chdir` command is a system call used in programming contexts, not directly in the command line interface for changing directories. The `pwd` command is used to print the current working directory, providing information about where the user currently is in the file system but not for changing locations. The `mv` command is primarily intended for moving or renaming files and directories rather than changing the working directory.
