Answer

Answer:

A. Resistance is directly related to length.

Brief Explanations:

The resistance formula is $R = \rho\frac{l}{A}$, where $R$ is resistance, $\rho$ is resistivity (constant for a given material), $l$ is length, and $A$ is cross - sectional area. When other factors are constant, $R$ is directly proportional to $l$.
