Joven = Young
Perezoso = Lazy
Especial = Special
Timido = Shy
So, obviously, the right answer is "Especial". Because a prize can't be joven, perezoso o timido.
So:
Margarita recibio un premio muy especial.
P.S. in your options, you wrote "perezozo". The word is actually written "Perezoso" with s not z.
Hope this helps! :)
