The advice columnist Ann Landers once asked her readers, "If you had it to do over again, would you have children?" A few weeks later, her column was headlined "70% OF PARENTS SAY KIDS NOT WORTH IT." Indeed, 70% of the nearly 10,000 parents who wrote in said they would not have children if they could make the choice again. Choose the most appropriate assessment of this particular survey from the following:

A.Because the sample size of 10,000 is sufficiently large, the results can be trusted

B.Since the question is very clearly worded and all readers were given equal opportunity to write in their response, the survey is considered accurate.

C.The results should be regarded as potentially erroneous since 10,000 is not a very large sample from the millions of readers of the Ann Landers column and the margin of error will be huge.

D.Due to potential bias in the survey, (self-selected response and not everyone reads Ann Landers), the results should be regarded as potentially misleading.
