B,C Correct answer
Explanation

The 'touch' command in Unix/Linux has two main uses: creating an empty file (if it doesn't exist) and updating the timestamp of an existing file (to the current time). Both options B and C are correct. 'touch' does not create directories (use 'mkdir') or change file ownership (use 'chown').
