Answer:
the only differences are the "ser" and "estar"
Explanation:
I think Ser is more of a simple way to describe what happens, while Estar is more like describing how something happens.
For Ser: description, occupation, characteristics, time, origin, relationship
For Estar: Position, Location, Action, Condition, Emotion
(I don't have Spanish class, this is all from google :> obviously)
Hey!
While both are often used, the most accurate answer is probably answer a:
The "personal a" is necessary.
Why?
Well, when we say: "Quiero a mi esposo Jorge" we are talking specifically about the husband, that is: "lo quiero a él". Therefore, the "a" is usually used on these occasions.
