Which of the following has the highest value of resistivity?

Correct option is B

The correct answer is (b) Nichrome.
 Nichrome has the highest value of resistivity, making it a good choice for heating elements and electrical resistors.
 Resistivity (ρ): The property of a conductor that opposes the flow of electric current through them and is independent of the shape and size of the materials but depends on the nature and temperature of the materials is called resistivity.
 The unit for resistivity is the ohm-meter (Ω-m).
 Nichrome: 100 x 10^-8 Ωm - High resistivity, used in heating elements and resistors.
 Silver: 1.59 x 10^-8 ohm-meters (Ωm) - Very low resistivity, makes it a good conductor.
