Because this is a pnp transistor, so while biasing -Vcc is applied to it. Thus with reference to ground all the voltage are negative, so ground is the answer.

If we apply +Vcc then it will be max. Because maximum o/p can be Vcc. O/p can't more than Vcc. Then how can you say ground?

Please explain in detail.

When doing transistor biasing then all voltage are negative with respect to GND hence GND is most positive to other.

Because everything goes back to ground.

I guest PNP transistor is "on" when its base is pulled low relaive to the emitter.
