Explanation

ulimit is the correct answer because it is the shell built-in command that controls resource limits for processes in a user's session, including the maximum size of core dump files (set with ulimit -c). edquota and quota are disk quota management tools that control filesystem space and inode usage for users, not process resource limits. core is not a standard Unix command - it's just the name of the dump file itself. ktrace is a BSD kernel tracing utility used to record system calls, not to set resource limits.

Memory tip: Think of ulimit as "user limits" - it's the one command that puts a ceiling on what system resources a user's processes can consume, including CPU time, file sizes, and yes, core dump sizes.
