Which conclusion is derived from the waiters' rostering rules?

Explanation:
In rostering problems, conclusions come from applying if-then rules. Here, there is a direct rule that says if Katherine doesn’t work, Simon doesn’t work either. So when you know Katherine isn’t on the schedule, you can conclude that Simon isn’t on the schedule as well. That straightforward implication is why this statement is the correct derived conclusion from the rules. The other options would require additional links or rules that aren’t guaranteed by the given rostering rules, so they aren’t necessarily derived.
