B. cells that continue to replicated even when not needed and does not stop
C. cells that move to G0,the resting phase
D. cells in hypotonic, solution to burst

B!

Explanation:

Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.

P.S. This is my first biology answer! Did I explain it good enough?

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
