ANSWER
The options (i) and (iv) are correct.
Aluminium is ductile and has high electrical conductivity and this property is not useful in the making of utensils.
Aluminium has good thermal conductivity and high melting point.
The commonly used metals in making utensils are copper, steel (alloy of iron) and aluminium.
Copper and aluminium are the most preferred due to their conduction of heat
Answer:
Copper
Explanation:
Copper is a good conductor of heat. So, it will allow heat to pass through it very easily, without using much fuel.
