A. The resistance decreases.

B. The resistance alternates between high and low values.

The resistance should decrease, less energy is required to pass all the way through the wire, where as a long wire would need a large amount of anergy to be able to reach from one end to another.

Answer:

option (A)

Explanation:

The resistance is defined as the obstruction offered by the material in the path of flow of electrons.

The resistance of a conductor is directly proportional to the length of the conductor and inversely proportional to the area of crossection f the wire.

As the length of the wire decreases, the resistance of the wire also decreases.

Option (A) is correct.
