Dry Ice is nothing but

Correct option is D

Dry ice is the solid form of carbon dioxide (CO₂).It is primarily used as a cooling agent due to its ability to sublimate directly from solid to gas without forming a liquid.

Key points:
● Dry ice maintains a temperature of approximately -78.5°C (-109.3°F).
● It is widely used in refrigeration, preservation of perishable goods, and creating fog effects in stage productions.
● Its sublimation property makes it clean and residue-free for cooling purposes.
● Handling dry ice requires precautions like insulated gloves to prevent frostbite.
● It is non-toxic but must be used in well-ventilated spaces to avoid CO₂ buildup.
● Dry ice is manufactured by compressing and cooling CO₂ gas into its solid state.

• Washing soda is sodium carbonate (Na₂CO₃)
  
• Carbon monoxide is a toxic gas
