The answer should be a) i only

Because, Aluminium is lighter than copper,
ii) is wrong beacuse it's lighter not heavier than copper
iii) is wrong because solubility has nothing to do with the conduction of electricity nor is a necessary property for using it for overhead cables.


Hope this helps.

Cynefin: thanks

It has a low density and high conductivity, so it can transport current with minimal losses, while also being light enough to not need large support structures. However, pure aluminium (used in overhead cables) is not very strong so these cables are reinforced with steel.
