B)1 - â
C)1 - .95
D)1 - z

The probability of not making a Type I error is equal to 1 minus the significance level (represented by the symbol á). This is because the significance level represents the maximum probability of rejecting a true null hypothesis, so subtracting it from 1 gives the probability of not rejecting a true null hypothesis (i.e. not making a Type I error).
