The correct answer is B) a sample that has the same general characteristics of the target population.
The best definition of a representative sample is a sample that has the same general characteristics of the target population.
In polls or surveys, researches use representative samples because it is very difficult to apply the surveys or polls to an entire population. So researchers use a sample that has the same general characteristics of the target population in order to have a valid representation and then, the results can be correct or generate a tendency.
