Took a World Geography with the same question and got a hundred, and the correct answer is B. (Courtnei, A is wrong answer.)

what were the rest of the answers

The probable explanation for why there are many endemic plants and birds in New Zealand but no native mammals is option B: plants and birds would make ocean crossings to isolated New Zealand islands, mammals could not.

To understand why this is the case, you need to consider the geographic isolation and unique geological history of New Zealand. The country is located far away from any other major landmass, separated by the open ocean. This isolation means that land mammals, which rely on land connections to reach new territories, could not naturally reach New Zealand.

On the other hand, birds and plants have the ability to disperse over long distances by flying or floating, either by crossing the ocean directly or by using temporary land bridges that may have existed in the past. This allowed for the colonization of New Zealand by various bird species and plants over time.

It's important to note that while New Zealand lacks native land mammals, it does have marine mammals such as seals and dolphins, which can swim and traverse the ocean independently.

Therefore, option B provides the most reasonable explanation for the absence of native mammals in New Zealand.
