Answer 2

Answer:

d)

Explanation:

We know that resistivity is a material property. And it has formula which is,

• R = pL/A

Where R = Resistance

p = resistivity

L = length

A = Area of cross section

• So we can say by using this given formula that Resistivity depends upon --

1. Resistance of the wire
2. Length of the wire
3. Area of cross section of the wire

Hence , we can check that only option d) is correct as it says all the above.

Also resistivity depends upon heating.
