An alpha level of .05 means there is a maximum 5% chance of rejecting a true null hypothesis, which is the basis for hypothesis testing. Option (A) suggests a probability for the null hypothesis, which is not correct. Option (B) suggests a probability for the alternative hypothesis, which is not correct either. Option (D) pertains to Type II error, which is not directly related to the alpha level.
