All of the choices (A, B, and C) are typically used in classical variables sampling. The mean-per-unit technique involves calculating the average value of a characteristic for each unit in the sample. The difference technique involves subtracting the expected value of the characteristic from the actual value to obtain the difference, which is then used in the analysis. The ratio technique involves dividing the value of one variable by the value of another variable, which is used to analyze the relationship between the two variables. Thus, all three techniques are used in classical variables sampling.
