Answer and explanation:
Before answering this exercise we need to remember three things related to grammar:
1. In spanish, a conjugated verb (verb nucleus) codifies aspect, mood, voice, tense and number.  
2. We use personal pronouns to identify the subject or object of a sentence; the subject also can be expressed by a noun (substantive).
3. The conjugated verb need to match with the subject of the sentence in number, no matter if it is expressed by a personal pronoun or by a noun.  
<h2>SIMPLE PRESENT TENSE
</h2>
Simple present in spanish is used to express:
- Things that are happening in this precisely moment
 
Example: Yo como pizza (I eat pizza)  
- Things that are commonly true  
 
Example: Los estudiantes hacen la tarea (Students do homework)
Example: Yo desayuno banana (I have banana for breakfast)
- Future actions that are totally planed and scheduled  
 
Example: Viajamos a casa (We travel to home)
