उत्तर

Both A and R are true but R is not the correct explanation of the assertion.

Both statements are true: chromatin condenses and coils to form visible chromosomes during cell division, and it includes euchromatin and heterochromatin. However, the two chromatin types do not explain chromosome formation by supercoiling.
