The question is asking for sentences using personal pronouns to describe the likes or preferences of different people. Let's analyze each option:
1. Clara: Since the question asks for sentences using personal pronouns, we can rephrase the sentence using the pronoun "ella." For example: "A ella le gusta leer libros."
2. Pedro y Juan: Similarly, we can use the pronoun "ellos" to refer to both Pedro and Juan. An example sentence could be: "A ellos les gusta ir al cine juntos."
3. Rocío y yo: We can use the pronoun "nosotros" to refer to both Rocío and the speaker. For example: "A nosotros nos encanta bailar salsa."
4. Mateo: To describe Mateo's preference, we can use the pronoun "él." For instance: "A él le gusta escuchar música clásica."
5. Héctor: Finally, for Héctor, we can use the pronoun "él" as well. For instance: "A él le encanta jugar videojuegos."
