The mean of a z-score distribution is always 0 because the formula for calculating z-scores involves subtracting the mean from the raw score and dividing by the standard deviation, resulting in a distribution with a mean of 0. The standard deviation of a z-score distribution is always 1 because the formula for calculating z-scores involves dividing by the standard deviation, resulting in a distribution with a standard deviation of 1. Therefore, the correct answer is D, with a mean of 0 and a standard deviation of 1.
