The best choice is B because at ratio level there is an absolute meaning of zero, which means that zero represents the absence of the variable being measured. In interval level, the zero point is arbitrary and does not represent the absence of the variable being measured. Option A is incorrect as interval level is commonly used in statistical analysis. Option C also incorrect as interval level does not have an absolute meaning of zero.
