Solution

The correct option is D Good thermal conductivity
  • For cooking utensils, the materials should be able to transfer heat, to cook food. They should be able to withstand high heat and should not corrode.
  • Aluminium has a good thermal conductivity, a high melting point and it is resistant to corrosion.
  • It reacts with oxygen to form a protective layer on its surface which prevents the corrosion of metal.
Hence, because of these properties aluminium is used to make cooking utensils.
