(D) Silver;
then copper, gold, and aluminum in that order.
Silver pound for pound is the best conductor of electricity
and has the lowest resistance.
Copper is most commonly used since it is very inexpensive
and is only slightly less of a conductor than silver.
Gold is used mainly because of it's reliability and ability
to not tarnish over time though it is the most expensive of
the four.
Aluminum is the fourth best conductor and is used primarily
in housing wiring for inexpensive purposes. The only
problem with aluminum is since it is such a light metal, it
shows unreliable over time and tarnishes easier as well.
