Only the last statement is correct.
Brief reasons:
- Charging by conduction requires a charged object to touch a neutral object so charge is transferred; after contact the objects end up with the same sign (not opposite).
- Charging by induction uses a nearby charged object (no direct contact with the object you want to charge) and usually a grounding step; the isolated object can be left with a net charge opposite to the inducer.
So (1) false (induction does need a charged inducer), (2) false (conduction needs one charged and one neutral), (3) false (conduction requires contact; induction does not), (4) true.
