jacked bike up today ,when i turn rear wheel there is noise coming from drive sprocket/would this be clutch or drive bearing

You may want to take the chain off and see if there is any play in the sprocket. Try to wiggle it up and down and side to side. also without the chain and in neutral spin it by hand to see if you can feel any odd drag or ruff spots. That may give some indication if it is the bearing.
