Sequential sampling is a type of sampling where the sample size is not known in advance, but a decision rule is stated before the sampling begins. This rule indicates whether sampling should be continued or whether enough information has been obtained. This type of sampling is useful when the cost of obtaining additional samples is high or when the sample size cannot be determined before the study is conducted. Therefore, the best choice for this question is A) sequential sampling.
