Answer 1

The correct option is C

(a) - (iii), (b) - (i), (c) - (iv), (d) - (ii)

Gold is used to make ornaments because of its metallic lustre (shiny surface) and it is chemically inert.

Copper is the most preferred metal to make electrical wires because it is ductile, a good conductor of electricity and most importantly it is economical.

Aluminum is used to make foils to wrap food and also to make kitchen utensils.

Tungsten is used to make bulb filaments because of its high melting point.
