3 days is the correct answer, I believe.
The answer is "Yo"
this is the answer because "Laura" is saying her opinion.
Not "nosotros"(we) because she is talking about herself.
Not "tu"(you) or "ellas"(they fem.)because it doesn't match up with the verb used in the sentence "creer".
Miguel fell to the floor in the past, which means that the eating also happened in the past. Therefore Horacio y Fernando ate in the past - we need a past tense.
almorzábamos is for first, not second person plural, so it's ungramatical.
<span>almuerzan is present tense.
From the options, the best one is </span><span>almorzaron, but actually you should rather use a continuous tense - almorzaban. </span>
