Answer:
B. Es la cocina.
Step-by-step explanation:
Well in the picture we see that it is a kitchen, obviously. So we just need to know what it is in Spanish. Well first of all, Es means it it in Spanish. La and el is used for the English word "the" in Spanish, it always depends on what we're talking about when saying la and el. Then we get to the big words. Here:
Sala de estar = living room, which isn't the kitchen which makes this statement false.
Cocina = means kitchen, so Es la cocina would make this statement true, which it is saying in English "It is the kitchen"
For knowledge, here are the others:
Bano = Bathroom
Dormitorio = bedroom
Hope this helps! You're lucky to get an explanation lol cause I'm busy.
