Question

Eres Lucía;

Answer 1

Answer:

Estás delante del sofá.

Explanation:

The question tells you that YOU are Lucia. So, you would use "you" instead of "she", so use estás instead of está.

She is not next to a door, so she is not "al lado de la puerta". She is in front of the sofa, so she is "delante del sofa".

Eres Lucía; estás delante del sofá.

Hope this helps!

Está delante del sofá would be the answer
