The correct answer is C. Del *.txt.

The command “Del .txt” will delete only the file named .txt. The command “Erase .txt” is equivalent to “Del .txt”. The command “Del ./p” will delete all files in the current directory and all subdirectories.

Here is an example of how to use the command “Del *.txt”:
