Answer:
a. less for a poor person than it is for an average-income person
Explanation:
Life expectancy may vary according to social class, ie, the better one's income, the higher the life expectancy, while the low income class has much lower rates than those with high purchasing power and consequently has lower life expectancy. With this, we can say that in relation to life expectancy, a poor person has a lower life expectancy than a middle income person.
