Sagot :

It’s is c :) that’s the best choices

Answer: A

Explanation: It most definetly not B, becuase not every form of life has DNA. A chromosome is a single chain of DNA that is coiled and super coiled to form dense thread-like pieces. The term chromosome is derived from the Greek words "chroma" or color and "some" or body and is so named because chromosomes have the ability to be stained with dyes.
