Explanation:

Correct option 2: Independant

Lets analyze other options

Optional – This makes no sense in the context. A bookstore isn’t described as "optional." 

Independent – This is word-for-word from the passage and fits perfectly.

Artistic – While the store might host creative events, the passage doesn’t call it artistic. 

Outstanding – This is a compliment, but again, it is not stated in the passage. 

Final Answer: 2. Independent
Because it’s explicitly mentioned in the passage and fits both grammatically and contextually.
