B.  It could melt and boil if thrown into a campfire.

"In fire tests on aluminium materials, when the temperature exceeds the melting point, in the range 600-660°C, the aluminium surface exposed to the fire can be seen to melt, but it does not burn."(www.alfed.org.uk/files/Fact%20sheets/11-aluminium-and-fire.pdf)

The metals are elements which have low ionization potential and can lose electrons easily

the other physical characteristics associated with them and hence with Aluminium are

a) they can conduct electricity in molten state, hence It would only conduct electricity if it were melted.

b) It could be stretched into a thin wire. It means it is ductile.

In case of given aluminium metal the correct answer is

it could be stretched to thin wire
