water since our planet is like 70+% water and cold water can be turned to ice for a defensive stand and water is strong lol

I would take water because if you think about it water is almost everywhere. I would be able to use my power for offense and defense which would be nice.

water because that way i can survive without having to worry about behydration but also because the earth is made up of 70% water and being able to control all that would be cool

I obviously go with wind, because its practically everywhere, and you can use it to lift things and even sharpen wind to the point where it is like a blade and cut things. also, u can use it to control attacks thrown at u. shift the wind in another direction, and the attack misses.
