Answer:
The correct answer to the following question will be Option C (cp filename.txt destination).
Step-by-step explanation:
The command cp is a control-line tool for folder and directory copying. This allows transferring one or more documents or folders with tools for backup-taking and attributes protection.
The general syntax of using the cp command is:
cp SOURCE file DESTINATION file
For example:
cp firstname.txt destination
here, firstname.txt is source file name and destination is the destination file name.
Option A, option D doesn't follow the general syntax of cp command that's why these options are incorrect, therefore, option C is the right answer.
