Crumble to Dust v Ghost Quarter

[Bilygote]

Situation:
Player A has an untapped {Ghost Quarter} on the battlefield

It is Player B's turn

Player B plays {Crumble to Dust} targeting Player A's {Ghost Quarter}

Player A responds by activating {Ghost Quarter}'s land destroy ability and targets one of Player B's non basic lands

How does this resolve?

[Rass]

Ghost kills a land and crumble fizzles because no target.
