In what type of matter are atoms most tightly packed?

WalksBySelf, Either you don't know what it means in "Science-y" terms or it's just how they explained it??? Should be better if you research on Google though... I only understand like 75 percent of it I think so...

Never choose options named as "All" and "Nothing". It's like falling for a scam 😂😂😂. And also, the people who got this question wrong hates Science 😂😂😂(or don't know much)

The first paragraph of the explanation makes no sense
