Probability samples are advantageous to the researcher because the method by which they are selected limits conscious and unconscious sampling bias and the accuracy or representativeness of the sample can be estimated. Option (D) is also correct but includes the unnecessary statement "they are perfectly representative of the population from which they are drawn" which is not always true, as even probability samples have sampling error. Therefore, option (E) is the best choice as it provides a more precise and accurate description of the advantages of probability sampling.
