To construct the cladogram based on the given DNA similarities, we look at the percentages of DNA shared between the organisms and humans.
- Organism C shares 90% of its DNA with humans, making it the most closely related.
- Organism A shares 85%, making it next in line.
- Organism B shares 80%, making it the least closely related.
Therefore, the order from least related to most related should be:
B, A, C, humans
So, the correct response is:
B, A, C, humans.
