Standardization of a variable involves converting it to a standard normal distribution with a mean of 0 and a standard deviation of 1. This is achieved by subtracting the mean of the variable from each data point and dividing by the standard deviation. Therefore, the correct option is C, which involves subtracting off the mean from the variable and dividing by its standard deviation.
