Explanation:
If the sentence has changed you would have to put a period.
The first answer is correct since you are only supposed to put information that clarifies the sentence in parentheses. Only putting dinner in parentheses wouldn’t make sense since it is a crucial part of the sentence, nor would you only put 6:30pm in parentheses since you already have about outside of the parentheses so saying As soon as we had finished dinner it was about, I started my homework.,Doesn’t make sense that means that even if you put things in parentheses the sentence should still make sense if the parentheses aren’t there.
I hope this makes sense if not please comment and I can try to explain it better :)
