Question Which method is the right one when using an anti static wrist strap?

[Ryz3301]

I'm trying to build a pc with the Cooler Master Q300L and this is my first time ever, building a pc.

So i decided to buy an anti static wrist strap (just to be safe + i'm a paranoid guy). And i've read so many methods on how to use the wrist strap and i just don't know which one is the recommended one.

People say:

1. Clip the alligator clip on the psu while it's turned off, but connected to a wall outlet

2. Clip it on the bare metal part of the case

3. Attach it on the metal prongs/grounding pins of an outlet (my country's socket type is F)

So which is correct?
