Answer:

D) it allows us to use chance to create groups that are similar to the population.

Step-by-step explanation:

A study is created in which the participants were randomly assigned to groups for different treatments. This was done as it allows us to use chance to create groups that are similar to the population.

Random assignment is the use of chance, to make sure that every participant has the same chance to be selected in groups. These divided groups can be experimental groups or treatment groups.
