Solution 1

If only assumption II is implicit   


Though it is given in the statement that earth may lose many of its species if it would lose all of its species cannot be commented on. Thus, the assumption I am not implicit. Since there is talk of saving many species by studying them scientifically, therefore it is desirable and possible to study many animal species. Hence, assumption II is implicit. 'If only assumption II is implicit' is the correct answer.

Solution 2

If only assumption II is implicit   


It is clear from the given statement that the scientific study of many animal species is possible, also it is desirable to study many species of animals that are still not studied scientifically.
