Final answer:

Decreasing the cross-sectional area of a wire increases the resistance due to its inverse proportionality.


Explanation:

Decreasing the cross-sectional area of a wire while keeping other factors constant will increase the resistance. This is because resistance is inversely proportional to the cross-sectional area of the wire. When the area is reduced, the resistance goes up. It's like adding more resistors in series which increases the overall resistance.
