I thought it was A at first, but tee makes more sense.

I remember practicing with similar questions, and I think "tee" is the command that writes to both standard output and a file.

I think the command we're looking for is the one that can duplicate output, but I'm not entirely sure which one it is.

"less" and "more" are definitely for viewing files, so I don't think they would work for this.

Okay, I've got this! Opening and reading data sources is definitely part of the Input Phase, where the raw data is brought into the system. The other options don't quite fit with that description.
