Answer:
The answer is D) All four species may be related, but each would have a unique scientific name using binomial nomenclature.
Explanation:
(Original chart was not attached, make sure to include it in your questions)
Using the process of elimination, you can eliminate options A and C. Option A is incorrect because there is a visible relationship between each of the species, hence the phylogenetic tree, and the branches connecting each one. Option C is incorrect mainly because we cannot determine if W is extinct based on the chart.
Now as you're left with options B and D, you can knock B off the map because X and Y may have the same species, but either way this cannot be established because we are unknown of each organism and their species.
<em>The surest answer will be D as they are evidently all related, and each would have a unique scientific name due to binomial nomenclature. </em>
