Answer

Brief Explanations:

The resistance of a wire is directly proportional to its length according to the formula $R = \rho\frac{l}{A}$, where $R$ is resistance, $\rho$ is resistivity (a property of the material), $l$ is length, and $A$ is the cross - sectional area. As length $l$ increases, with $\rho$ and $A$ constant, resistance $R$ increases.

Answer:

B. The resistance increases.
