The correct answer to the question is C).Dry ice changes to carbon dioxide when kept in an open container.
EXPLANATION:
Before answering this question, first we have to understand sublimation.
Sublimation is a thermal process of state or phase change in which solid substance is directly converted into gas without melting i.e the substance won't undergo liquid state.
In the given question, dry ice is given. Dry ice is the solid state of carbon dioxide. When the dry ice changes to carbon dioxide, directly solid carbon dioxide is converted into gaseous carbon dioxide. No liquid carbon dioxide is formed . So, the phase change is from solid to gas.
Hence, the conversion of dry ice into carbon dioxide is an example of sublimation.
