b. surviving members of the white majority live longer than members of low-ses ethnic minority groups.
c. differences in rates of chronic illness between high-ses and low-ses groups increase with age.
d. men outnumber women by a ratio of about 3 to1.

Answer 1

I believe the answer is: A. surviving members of low-SES ethnic minority groups live longer than members of the white majority.

Surviving members of low SES status tend to live in poor unhygienic neighborhood with little access to proper nutrient.
But, if these people survived until the age of 85, it indicates that their body possess a great capabilities of self-protection/repairment, which help them to elongate their ife span.
