When standardizing paired data, we typically convert both X and Y to z scores. This allows us to compare the relative positions of each data point within their respective distributions and determine if there is a significant relationship between the two variables. Dividing everything by the standard deviation of X (A) or converting X to a T score (B) would not take into account the variability of both X and Y, while subtracting the mean from each value of X and Y (D) would only center the data around zero and would not adjust for the different scales of the variables.
