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.
