Traits with Morphs -your choice-

There's a number of traits that have me rather confused. I'm specifically talking about traits like:

- Burning Claws 12pts (Natural Weapons): Claws 1 - Your Choice - Melee Only, Bio-fire Extremis 1 (Claws Morph)

- Arcing Talons 12pts (Natural Weapons): Talons 1 - Your Choice - Melee Only, Bio-Lightning Extremis 1

(Talons Morph)

Whatever does the "-your choice-" part here mean? Can you take either the talons or the bio-lightning extremis 1 (shouldn't that be bio-electricity, btw?)

I'm making a lv2 Ursidae Biest class that I'd like to have the Arcing Talons trait, but if I -need- to take both the Talons 1 ánd the bio-elec1, then I won't be able to do that (because bio-elec has properties X+1). That'd be okay, but idk what's the case currently :' )

Note: I know you need Talons for the bio-elec in this case since it's a Talon morph, but I've got a way to give my class talons before taking this trait.
