Answer:
The correct sentence is:
- Mira ese pez tan grande.
Explanation:
Though in English the usual order of a sentence is: Substantive/verb/complement, in Spanish, is more free, in some occasions you could see a sentence beginning with the complement and finishing with the substantive, but in this case is the one thing that changes is that the noun is tacit (it means that is not written because the verb make reference to it), the noun, in this case, is "tú", after the verb is "mira" and the complement "ese pez tan grande".
