By reading the sentence I would put
A mi maestro le gusta escribir en la pizarra.
But, there are many adjectives in Spanish that would suit this sentence. Tell me if this is what you need, if not let me know....
The third one because tres means three and there are 3 in a trio
Hi there!
The answer is D. ¿Cómo está usted?
“Usted” is used formally for anyone older or in a higher rank than you. When addressing a teacher you say “usted”.
Hope this helps!
