The correct answer is **A. 450 g**.
Sublimation is a phase change where a solid turns directly into a gas without passing through the liquid phase, and the mass of the substance remains the same during this process. Therefore, if a solid with a mass of 450 g sublimates, it will produce gas with a mass of 450 g as well.
