Aperson in cardiac arrest: is unconscious. is not breathing normally. has no heartbeat. all of the above.

Typically Cardiac arrest is "Has no heart beat" hence cardiac only refers to the heart. But it ciuld be a trick question because in a cardiac arrest the person is not breathing and is unconscious as well. But i would go with "Has no hearbeat"

I'd say replacing that habit (of smoking) with a more healthy habit, like going to the gym. c;
