Answer:
C. Comedor (or dining room) is the correct answer.
Step-by-step explanation:
In this sentence, the word "abajo" means "downstairs," assumingly in a house.
The word "Bano" means "bathroom."
The word "Sotano" means "basement."
The word "Dormitori" means "bedroom."
All 3 of these rooms are usually found upstairs in a 2-floor house. However, the dining room is usually located downstairs.
Therefore, C. Comedor (or dining room) is the correct answer.
Hope this helps! :D
