1. A mi me gusta cocinar.
You need the objective pronoun me here, as well as the proper conjugation of the verb cocinar, which means to cook.
2. Hay un sofa en 4) la sala.
You didn't write this option here, but I found on the Internet that it is one of the options.
La cocina is a kitchen, el garaje is a garage, el jardin is a garden, and la sala is a living room.
