(d) Graphite
Explanation:
Though sodium and potassium are metals and show electrical conductance but graphite has more conductance due to presence of π-electrons in its crystal lattice. Sodium and potassium have only one electron in its outermost shell. So, inspite of being metal, their conductivity is not so good.
