#4 looks like a shoehorn. Is that even concave enough to use as a spoon? Likely not. That's out.

#3 is definitely not a spoon. No idea what it is, but it's not gonna work well as a spoon. Not gonna deal with that one.

#2 is actually a spoon, but a small one. It'll be frustrating to use forever. I'd prefer not to use it.

#1 is actually a decent sized spoon. Oddly shaped, but it'll hold a decent amount of food or liquid. I guess I could live with that one.
