To copy the file command.com from drive c: to drive a: A. Drive c: copy drive a:\command.com B. C:A: copy command.com C. Copy c:\command.com a: D. Both b and c

The correct answer is C.

To copy a file from one drive to another, you can use the copy command. The syntax for the copy command is:

copy source destination

The source is the name of the file you want to copy, and the destination is the location where you

want to copy the file. In this case, the source file is command.com and the destination drive is a:. So, the command to copy the file command.com from drive c: to drive a: is:

copy c:\command.com a:

Option A is incorrect because it does not specify the destination drive. Option B is incorrect because it does

not specify the source file. Option D is incorrect because it includes both incorrect options.
