A pronoun replaces a noun in order to avoid repetition. In this way, subject pronouns function as the subject of a verb. These are the following subject pronouns in Spanish:
FIRST PERSON.
Singular: yo (I)
Plural: nosotros/nosotras (we)
SECOND PERSON.
Singular: Tú/usted
Plural: Ustedes/vosotros/vosotras
THIRD PERSON:
Singular: él/ella
Plural: ellos/ellas
So, solving this problem, we have:
1. The correct answer is:
c. ella (she). <em>Pronombre Tercera Persona del Singular (Femenino)</em>
2. The correct answer is:
c. él (he). <em>Pronombre Tercera Persona del Singular (Masculino)</em>
4. The correct answer is:
d. ustedes (you). <em>Pronombre Segunda Persona del Plural.</em>
5. The correct answer is:
a. ellas (they). <em>Pronombre Tercera Persona del Plural (Femenino)</em>
<u>Nota.</u> Ellos - Es válido tanto para el género masculino como para referirse a mujeres y hombres en conjunto. En 4. se usa el segundo caso.
This is how to conjugate the verb ESTAR (which means to be) in the present tense:
yo estoy, tu estás, el/ella/Usted está, nosotros estamos, vosotros estáis, ellos/ellas/Ustedes están.
Your sentence is I am home. In Spanish, the word YO stands for I in English. This means that you would use the form estoy in your example.
The correct answer is B. estoy.
You use preterite to describe an action that took place and was fully done, Ex. José entro a la habitación, you can see John went into the room, he completed the action. On the other hand, imperfect tense doesn't specificate if the action was completed, Ex. José entraba a la habitación, it doesn't tell us if José fully entered the room.
