The source book printed no answer; this one was worked out and checked — see the explanation.
Explanation
KC₈ has K between every layer, which forces AAAA (eclipsed) stacking; the transferred electrons make it metallic (paramagnetic, Pauli) and a better conductor than graphite. All three statements are correct.
