Explanation

GitHub Actions uses workflow commands via a specific syntax written to stdout. The format echo "::debug::<message>" is the official workflow command syntax for printing debug messages to the log. These messages are only visible when debug logging is enabled. Option B writes to a non-existent variable, option C uses add-mask which is for masking sensitive values, and option D uses a malformed GITHUB_OUTPUT syntax.
