D looks interesting, but I'm not sure if '2&>1' is the right way to redirect the error output. Hmm, need to double-check that.

I think E is the correct answer. Sending the output to a file and discarding the error output is a classic Unix trick.

Option A looks good, but I'm not sure about the syntax with the '2>' part. Seems a bit confusing.

Option A is correct. It redirects the error output to /dev/null while writing the normal output to a file.
