Answer:
The correct answer is:
- The sentence is gramatically incorrect.
Explanation:
The word that makes the sentence incorrect is:
está. Is used to be in a certain place or time.
- Tengo un perro que está muy tonto, siempre se quiere morder la cola.
The correct word to be gramatically correct is:
es. is used to describe a personality or an action the subject could be doing.
- Tengo un perro que es muy tonto, siempre se quiere morder la cola.
In this case the dog (perro) is fool (tonto) so the correct option is es.
