The results of a study based on a sample can have various sources of error, including office error (such as mistakes during data entry), sampling error (due to the fact that a sample is used instead of the entire population), noncoverage error (when some members of the population are not included in the sample), response error (when respondents may provide inaccurate or incomplete answers), and nonresponse error (when some individuals chosen for the sample do not respond or cannot be reached). Therefore, D, "All of these are correct," is the best choice.
