Detailed Solution

The given statement is true.
The electrical resistance of a conductor or wire depends on the nature of the material of which it is made. Some materials have low resistance, whereas others have high resistance. Electric resistivity is a fundamental property of a material that measures how strongly it resists electric current. It is also known as specific resistance and is directly proportional to the resistance of the wire.
Resistance,

R = \frac{ρ \times l}{A}

Where,
A is area of cross-section of wire

ρ

is resistivity of the wire and l is length of the wire
So if the resistivity of wire is three times then resistance of the wire will also be three times.
