Which file in MSDOS contain internal command that are loaded during booting process?

Solution (By Examveda Team)

Command.com is the executable file that serves as the command interpreter in MS-DOS and early versions of Windows.
During the booting process of MS-DOS, Command.com is loaded into memory. It processes commands typed into the command prompt and executes them.
Internal commands, such as DIR, COPY, DEL, etc., are built-in functions of Command.com and are available immediately upon booting.
Io.sys and Msdos.sys are system files in MS-DOS that are crucial for system operations but do not contain the internal commands loaded during the booting process.
Config.sys is a configuration file in MS-DOS that is used to configure the system at startup, but it does not contain internal commands.

Therefore, the correct answer is Option C: Command.com.
