Ответ:
B) A random sample may represent the population is your best answer.
Step-by-step explanation:
Note that the answer choice says "may", which means that it doesn't always represent the population. Random samples means that they ask random people, and do not have a certain rule that they have to follow (such as recipients can only be a certain race, age, etc.) and that they can ask anybody they meet. This can give not only a higher chance of a general population's opinion, but also makes sure that there is not a high chance of obtaining misleading information.
For example, a random survey would not take place at a rally, in which most of the people would believe the same thing, and would answer fairly the same for the survey. Instead, a random survey may be taken at a busy intersection during the time when most people are out. You must note that though it has the best chance of getting a more accurate representation, it still isn't the most accurate. For the best accuracy, everyone would have to answer the survey in which the survey question would affect.
