This is the best and correct answer. In this sentence, the verb ser is being used as occupation. Basically, it's what someone does for a living or as a hobby (pasatiempo means hobby). So es is the conjugation of the verb ser for the third person singular in the simple present. The simple present tense is used to talk about habitual actions or routines. This tense is also used to describe things that happen now or in the near future.
This is the correct answer. The word ellos is the subject pronoun for the third person plural in the simple present. This sentence is given in the reflexive form. We use this form with Reflexive Pronouns and verbs to point out that a person carries out an action to or for himself or herself. Therefore, se is the reflexive pronoun for the third person plural in the simple present and acuestan is the conjugation of the verb acostar also for this person and in the simple present.
