B. Largely determined autonomously by factors other than real income. C. A function of disposable income over a lifetime rather than the current period. D. An increasing proportion of disposable income against individual consumption. E. None of the above [it seems you can't explain to Jonathan a correct statement about consumption expenditures either!)
