AMaximum diversity - Population B;
Minimum diversity - Population C
BMaximum diversity - Population A;

Correct Answer
CMaximum diversity - Population A;
Minimum diversity - Population B
DMaximum diversity - Population B;
Minimum diversity - Population A
Solution
Species diversity is the number of different species present in a given population i. e. 'Species diversity relates to the number of different species.'
In population A, there are 3 different classes present. These are mammals, birds, and amphibians. Hence, it will have vast species diversity.
In population B, only 2 classes are present, namely mammals and amphibians. Hence, species diversity will be less compared to that of population A.
In population C, all the species belongs only to class mammals. Hence, it will show the least species diversity.
So the correct answer is option B.
