Answer:
well, what we can do here is eliminate what we know. It's not A, because ALL living organisms reproduce. (examples include humans, cows, plants, etc.) for now, until we see the other answers, we will skip b. It can't be C, because on a trusted website, it states that the unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory. ... All organisms are made up of one or more cells.
If we take a look at D, It could be true because in another trusted website, it states that Oxygen helps organisms grow, reproduce, and turn food into energy. ... Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration. So, Looking back up to B, it seems less likely now that we've viewed everything. D is the answer, I wasn't paying attention earlier, haha.
Hope this helps! brainliest is appreciated :)
