A compass needle normally points toward Earth’s magnetic pole, which is near the North Pole. Which best explains why the needle moves away from the pole when it comes close to a current-carrying wire?
-Current within the wire weakens the magnetic force of the pole.
-Magnetism surrounding the wire weakens the magnetic force of the pole.
-Magnetism surrounding the wire draws the needle toward the wire.

Answer

-Magnetism surrounding the wire draws the needle toward the wire.

Explanation
When a compass needle is placed near a conductor carrying current, it deflects to one side. 
This happens because the magnetic field due to the needle interact with electric fields around the conductor carrying carrying current resulting to a force that makes the needle to deflet. 
The best answer that suits the question asked is -Magnetism surrounding the wire draws the needle toward the wire.
