Considering the parallel question: best and most likely weapon used by a human.
Technological level is not stated so humans will be considered over the entire time span of their existence. For much of this time there was minimal technology and so the most likely weapon will be one made from natural materials.
Assuming an arm, brain and eye that works like a human: one great ability of the human is to judge distances and trajectories and one huge advantage humans have over animals is the ability to throw things. Projectile weapons are better than weapons that require close quarters because they decrease your chance of being hurt by your adversary, especially an adversary that does not have projectile weapons, like an animal.
Most likely projectile weapon is the one most readily available.
1: Low tech most likely.
2: Projectile weapon is best.
3: Low tech projectile weapon which is most available is most likely.
Your creature's best and most likely weapon is a rock.
No joke. Imagine a pro baseball pitcher with a pile of good rocks facing off against a pack of guys with swords starting 100 yards away. If the sword guys were well trained, confident and did not slow down, with luck a couple might reach him. Or maybe not. Now imagine the pitcher has 4 throwing arms.
