D strengthens the argument or is irrelevant, when the task is to weaken.


Humans can carry diseases without suffering--explains one way that humans who weren't themselves dying off could cause an epidemic.
Animals can carry diseases without suffering--again, explains how animals following the humans and native animals could spread the disease before they died.

Alternatively, as you point out, what an "individual" human or animal can do does not explain an extinction event, so you could write the choice off as irrelevant or unclear as to its effect.
