One of the common arguments why the process of transplanting non-human organs which came from animals may be considered as an ethical act is that antigens on the surface of the non-human organs are not significantly rejected in the process.

Answer:
sister taxa
Explanation:
Groups departing from the same evolutionary node are called sister taxa and are evolutionarily closer to each other than groups departing from another node. Thus, we can say that the sister taxa are evolutionarily closer (related) to each other than to the taxa that did not diverge from the same place. Similarly we can say that taxa that did not diverge from the same place, cannot be called sister taxa and are distant evolutionary.
Answer:

Explanation:
So, the answer would be B or D.
But, it is most likely B due to dampness.
