Explanation

Dry ice is the solid form of carbon dioxide (CO2). It sublimates at -78.5°C, transitioning directly from solid to gas without becoming liquid, which makes it useful for refrigeration and creating special effects. The correct option says 'Solid Corbondioxide' which is a misspelling of 'Carbon Dioxide' - the concept is correct but the spelling is wrong.

AI explanation

Dry ice is simply the solid form of carbon dioxide (CO2), used for refrigeration and special-effect fog because it sublimates directly from solid to gas without melting into a liquid. This sublimation property is what makes it useful and distinguishes it from ordinary water ice.
