Answer 2

Hello Dear,

◆ Answer - (A) dry-ice

Poles of Mars are covered by dry-ice.

● Explaination -

• Dry-ice is nothing but frozen carbon dioxide.
• It isn't found naturally on earth, but found at mars poles.
• During seasonal cold on mars, vapour CO2 is frozen to solid form known as dry-ice.
• When these ice-caps are exposed to sunrays dry-ice is directly converted to CO2 gas bypassing liquid state.

Thanks dear...
