Answer 2

As the electrical resistivity of a substance increases the resistance increases. (i.e Option d)

From this equation,R =  ρℓ/A, we can say that resistance and resistivity are directly proportional.

Electrical resistivity (also known as specific electrical resistance or volume resistivity) is a material attribute that determines how well it resists electric current. In an electrical circuit, resistance is a measure of the resistance to current flow. The Greek letter omega  represents resistance.
