Which best describes how DNA fits inside a cell nucleus?

DNA folds into stacked layers called chromatin, which then squeeze into the nucleus.
DNA is double-stranded, so one strand is inside the nucleus and the other wraps around the nucleus.
DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
DNA is naturally much smaller than the cell nucleus so it easily fits inside the nucleus.

Explanation:

3rd one

the DNA coils around histone octamer formed by histone protein.

Histones are basic proteins.

DNA is acidic in nature

so DNA coils around histone and fits into the nucleus.
