When we compute multiple confidence intervals or hypothesis tests, the probability of making at least one Type I error (rejecting a true null hypothesis) increases, which is known as the experimentwise error rate. Therefore, the value of α in this case is called the experimentwise error rate, and the correct choice is C. Comparisonwise error rate is another term for the familywise error rate, which is the probability of making at least one Type I error among a family of tests. Tukey simultaneous error rate and pairwise error rate are specific types of comparisonwise error rate that apply to specific situations, and they are not as commonly used as experimentwise error rate.
