If Onoki is ground level (which he would most likely be) Naruto's only Option is to Jump or go air born to truly dodge it! Why? Because the beam is not only fast and huge, when spinned around or simply used in a sweeping motion left to right or right to left

(onoki is at the bottom of the triangle, and the black space is him going back and forth with his Jinton Beam towards Naruto's Direction in a constant sweeping motion)
Now with that being shown Air born is the easiest thought (jump) but also dumbest! Why? because in the air you cannot move unless you can fly! Now ofc Naruto has his Clones, but he cannot spam clones while in sage mode so the more clones he use the faster his Sage mode will run out. Also we are forgetting the speed of Onoki when air born!
And this is just about Naruto who can use clones mid air to help move (not even going to bring up that his sage mode isn't even long and he needs to waist chakra summoning the 2 sages). But imagine other ninjas?
