It depends on how you designed your game. You can put all sprites with countries on the layout, outside of the visible area. Pick two random sprites and display their animation names as wrong answers. Destroy those sprites.
Then pick one random sprite, move it to the visible area and display its animation as the right answer.
.
Or if you have an array with all country names, display three random names. Then pick one of them at random (correct answer) and set the sprite animation to it.
