Good job eliminating option D. Option A is reversed Mitosis occurs in somatic cells and Meiosis in germ cells. Crossing over results in genetic diversity or a change in DNA, that would happen in reproduction and thus meiosis. Option A, B, and D are not the answer. <u>Option C is correct.</u>

DNA
Explanation:
DNA is composed of two complementary strands oriented antiparallel to each other with the phosphodiester backbones on the exterior of the molecule. The nitrogenous bases of each strand face each other and complementary bases hydrogen bond to each other, stabilizing the double helix.
