My answer also will be #4, see the following difintions of both deranged and disrupted:
someone who is deranged behaves in a crazy or dangerous way, usually because they are mentally ill.
dis‧rupt /dûs"ršpt/ [transitive]
to prevent something from continuing in its usual way by causing problems.Pay attention to the underlined.
I hope this would be clear to know why the answer is only #4.
