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.
The pattern I see is that you confuse number and gender.
- *Estos libro → It is not written in the plural because it speaks <u>only</u> of a <u>book</u>.
- Esos plato → It is not written in the plural because it <u>only</u> speaks of one <u>dish</u>.
- Aquellos carros → It is not written in the singular and masculine because it speaks <u>many</u> <u>cars</u> (masculine).
- Aquellas casas → It is written in <u>feminine</u> because it talks about some houses (feminine).
