D? B came pretty close too.

Notice that the biologist hints at reducing the current pace whereas the politico says to stop the process altogether. that distinction made me choose D over B.

IMHO

IMHO it should be B, B is consistent with what biologist says as rate of deforestation is not the only factor causing extinction, also it contradicts politician that although deforestation is stopped still Koala becomes extinct.

D does not contradict politician,

IMO D

Deforestation slows = koala survives (stimulus: Deforestation continues = koala approaches extinction)

IMO B, because:

Bilogist says:
“If the forest continues to disappear at its present pace, the koala will approach extinction,”, which implies that Deforstation should be stopped.

Politician says:
“So all that is needed to save the koala is to stop deforestation,”, which implies if Deforstation is stopped, Koala will be saved.

Option B is consistent with what Biologist says, which is to stop Deforstation and is not consistent with what Politician expects, which is inspite of Deforstation being stopped, Koala becomes extinct.

How can B be inline with what biologist is saying?
B says that
"(B) Deforestation is stopped and the koala becomes extinct."
Biologist is saying:
“If the forest continues to disappear at its present pace, the koala will approach extinction,”
which means that if deforestation is not stopped, Koala will extinct.
So how can both the statements true at the same time???

Deforestation continues and koala approach extinction : Biologist

Stop deforestation and that is all needed and koala survives: Politician

The nearest is the option B.
It says "Deforestation is stopped and the koala becomes extinct. " Deforestation is stopped and if koala survive, it would be in accordance with the politician.
It is thus in line with both the approaching extinction and deforestation not being the only cause.

Option D is also inline with politician's view apart from being supportive of the biologist.
