Choose the correct statement

a.The 30-nm fiber is further folded, results in 10000-fold compaction in euchromatin in interphase chromatin and in mitotic chromosomes to achieve an overall 10,00- fold compaction in euchromatin.

b.This 30-nm fiber is further folded, results in 1000-fold compaction in euchromatin in interphase chromatin and in mitotic chromosomes to achieve an overall 10,000- fold compaction in euchromatin.

c.Heterochromatin generally maintains 10,000-fold compaction in both interphase and mitosis after 30 nm.

d.Heterochromatin generally maintains 10,00-fold compaction in interphase and 10,000 folds in  mitosis after 30 nm.
