The self-identification variable is a discrete variable, as it involves participants checking one box from a list of three distinct categories (low-income, middle-income, or high-income). On the other hand, the dollar-figure variable is a continuous variable, as it involves participants providing their annual income in dollars, which can take on any value within a certain range (e.g. $30,000, $42,500, $71,832.47, etc.). Therefore, B is the correct choice.
