If H ₀ is true and the probability of making a Type I error is 0.05, then the significance level (alpha) is 0.05, meaning there is a 5% chance of rejecting the null hypothesis when it is actually true. This also means that the probability of making a correct decision (not rejecting the null hypothesis when it is true) is 1 - alpha, which is 0.95 or 95%. Therefore, the correct answer is C.
