Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

By default, echo * expands the glob * to list all files in the current directory. 'set -f' (or 'set -o noglob') disables glob expansion, causing * to be treated literally. 'set -t', 'set -m', and 'set -l' control other shell options and don't affect globbing.
