2. Good electrical conductivity
3. Ductility
4.  High melting point

विकल्प

• (i) and (ii)

• (i) and (iii)

• (ii) and (iii)

• (i) and (iv)

Answer 1

(i) and (iv)

Explanation - 

Aluminium is used for making cooking utensils because it is a good conductor of heat and has a high melting point of about 660 °C. So, when on top of a stove the aluminium vessel would not melt while cooking.
