Arrange the given steps of DNA packaging in correct sequence?
(A) Histones are organized to form a unit of eight molecules called histone octamer
(B) Nucleosomes form a structure of repeating unit called chromatin
(C) A set of positively charged, basic proteins are called histones
(D) A negatively charged DNA is wrapped around the histone octamer to form a structure known as nucleosome
Choose the correct answer from the options given below:

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
