Answer: (b)the results of the survey cannot reliably be extended and generalized. Step-by-step explanation:Voluntary sampling is a type of convenience sample; it is appropriate that the researcher is going to perform. However, voluntary sampling can lead to bias; generally only people who feel strongly one way or the other about the survey is going to volunteer to be members of a sample.Since there is a possibility of bias, the results of the survey cannot reliably be extended and generalized.
