God, if I could choose, I would say none. All of these lead to inequality (because circumstances vary between many individuals) but I believe prestige should hold the most weight in determining social class. Prestige (which is respect, recognition, or regard) is based on many criteria, including wealth, family background, fame, leadership, power, occupation, and accomplishments. Leadership, power, and accomplishments can both be achieved by any individual with hard work. This is still an unfair balance (gender inequality, racial/ethnical inequality/racism) because of individual factors, it still leaves hope for some people to rise the social ladder.

In the given options, Option 1, amount of tar cigarette, is both quantitative and continuous as it have numeric value between any two values.
3. Time is measured and can range between any two values (to walk from parking area to classroom) so it is both quantitative and continuous.
