Resistance of a conductor does not depend upon.

When a potential difference is generated across a conductor, it has the power to resist or oppose the flow of charges through it. It is determined by the substance used. It is also affected by the shape and size of the conductor.
The capacity of a conductor of a particular length (l) and cross sectional area (A) to resist or oppose the flow of charges through it when a potential difference is produced across the conductor is referred to as resistance.
The resistance of a particular conductor is determined by the length and cross sectional area of the conductor.
A conductor's resistance is proportional to its length and inversely proportional to its cross sectional area.

This indicates that if two cylindrical conductors have the same cross sectional area but one is longer in length than the other. The resistance of the longer conductor will be greater than that of the shorter.
If two cylindrical conductors have identical lengths but one has a larger cross sectional area than the other, the resistance of the conductor with the smaller cross sectional area will be greater than the resistance of the conductor with the larger cross sectional area.
The resistivity of a conductor's substance also influences its resistance. Resistance is proportional to the resistivity of the conductor's substance. As a result, the resistivity will be equal to the resistance of that conductor.

Consider the length l and cross sectional area of a conductor. A. Assume the material's resistivity is $\rho$.

The conductor's resistance R is expressed as $R=\frac{{\rho }^l}{A}$.
The resistivity of a conductor varies with temperature. When the temperature of the conductor rises, its resistivity rises, and when the temperature of the conductor falls, its resistivity falls.
Because a conductor's resistance is directly proportional to its resistivity, resistance increases with increasing temperature and decreases with decreasing temperature.
As a result, the resistance of a conductor is determined by its length, thickness (i.e. its cross-sectional area), and temperature. It is not affected by the conductor's dampness.

Hence, the correct answer is option D.
