Increasing Order of Resistivity of Materials

Arrange the following materials in increasing order of their resistivity: Nichrome, Copper, Germanium, Silicon
Copper < Nichrome < Germanium < Silicon
Germanium < Copper < Nichrome < Silicon
Nichrome < Copper < Germanium < Silicon
Silicon < Nichrome < Germanium < Copper

Solution:

Copper is a conductor (lowest resistivity), Nichrome is an alloy (intermediate), Germanium and Silicon are semiconductors with Silicon having a larger bandgap and thus higher resistivity.
