Question

That's the most amazing skateboard trick I've ever seen!" my friend Tommy said. "That's _______!"

Answer 1

Since tommy is exclaiming and he says, most amazing, he proably can bealive it, so you use unbelavable. Brainlest? I need it.

Answer 2

I believe it is A.
The reason why is if a trick is amazing you would not see it very often, so it is unbelievable.
Hope this helps!
