D Correct answer
Explanation

DNA carries all the genetic information about an organism - it contains the complete blueprint for building and maintaining that organism. Blood cells (RBCs, WBCs, platelets) do not contain DNA or carry the organism's genetic information - RBCs lack nuclei entirely in mammals.
