Which of the following statement is true regarding second level of organization 

a. The second level of organization is the coiling of the 10-nm fiber of nucleosomes into a helical array.

b. The coiled helical array to constitute the fiber of diameter 30 nm that is found in interphase chromatin and in mitotic chromosomes.

c. This compacts the DNA - 40-fold. The structure of this fiber requires the histone tails and is stabilized by linker histones.

d. Histone H1, histone tails, and increased ionic strength all promote the formation of the 30-nm fiber.
