Answer 2

A suitable selection strategy for study of a large heterogeneous Universe is stratified random sampling.

Explanation:

It is impractical and impossible to study a huge population. So sampling is used to study the behavior or preference of a population. Sample is a set of observations drawn from a population. If the universe/population to be studies is too  large and heterogeneous, sampling allows us to study a selected small portion of population, enabling researchers to reach a conclusion based on the stratified random sampling or probability sampling.
