At certain times after combustion the unburned fuel particles get settled over the cylinder walls. Due to higher combustion temperature these particles burns spontaneously before normal combustion occurs. These regions are called Hotspots.

Yes. All options are right.
Preignition occurs when spark plug got overheated, it ignites the charge in between compression stroke & power stroke.
As earlier says that whenever cylinder surface getting hot it also ignite the charge before ignition.
