In what way are all living organisms on Earth similar?

The correct answer is A: They all use the same set of nucleotides.
All living organisms use DNA and RNA as their genetic material, which are composed of the same set of nucleotides (adenine, thymine, cytosine, and guanine for DNA; adenine, uracil, cytosine, and guanine for RNA). This shared genetic code is fundamental to the biological processes of all living organisms, allowing them to store and express genetic information.
