To answer this question, you need to understand the boot process of a computer and the files involved.

When you turn on your computer, the boot process begins. One of the first steps in this process is to check the control file, which contains important information about the operating system.

Option A) Command.com, io.sys - This option is incorrect because it only mentions two files, while the correct answer has three files.

Option B) Command.com, date.com, dir.com - This option is incorrect because it mentions three files, but none of them are the correct control file.

Option C) Command.com, io.sys, msdos.sys - This option is correct because it includes all three files that are part of the control file. Command.com is the command interpreter, io.sys is the input/output system file, and msdos.sys is the Microsoft DOS system file.

Option D) Chkdsk.exe - This option is incorrect because Chkdsk.exe is a utility used to check and repair file system errors, but it is not part of the control file.

Therefore, the correct answer is C) Command.com, io.sys, msdos.sys. This option is correct because it includes all three files that make up the control file.
