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.
I take Spanish as well and i hate to tell you the but the correct way to say "I prefer milk" in Spanish is( prefiero la leche) u are listing the correct ways to say (She runs to maintain health) look them up if u dont believe me type in on google (Ella correr para mantener la salud in English). Hope this helps
