The answer is B. Population parameter involves examining everyone who fits the description you are looking at, which is simply impractical if you’re surveying a large number of people. Studying a smaller sample of subjects is generally more doable but by using inferential statistics, it is possible to arrive at a close approximation to the population parameter.
