Shell escapes? What, are we trying to escape the shell itself? Nah, this is clearly about command substitution.

Output formatting? That can't be right. Backticks are definitely for running commands and getting their output.

Command substitution, of course! Backticks are a classic way to capture the output of a command and use it in your script.

Hmm, I think backticks are used for variable dereference, but I could be wrong. Let me double-check that.

Backticks are used for command substitution, which is the correct answer (C). I remember this from my shell scripting classes.

No, backticks are definitely for command substitution. They allow you to execute a command and use its output as part of another command.
