I would choose C.
It’s the most logical answer to me.
A) Northern and eastern Europe. hope that helps! God bless.
Id say the best answer would be the Sahara. Sublimation is going from a solid to a gas. Imagine an ice cube, it would be so hot that it would go from ice to its gas form of water vapor, instead of melting into water. In the Amazon, it would most likely just melt. In the attic, it wouldn't change. And again, it would only melt in Florida. Hope this helps.
