The ethnic diversity index (EDI) ranges from 0 to 1, where 0 indicates complete homogeneity and 1 indicates complete heterogeneity. To calculate the EDI in this case, we can use the formula:
EDI = 1 - (p1^2 + p2^2)
where p1 is the proportion of the population in the first group (80%) and p2 is the proportion in the second group (20%). Plugging in the values, we get:
EDI = 1 - (0.8^2 + 0.2^2) = 0.32
Therefore, the best choice is B.
