Characteristics used to classify a group of the population that shares common characteristics, such as age, gender, class, etc. is called D. demographics. Demographics is the term that sociologists use to denote a subgroup of people who all have the same qualities and can thus be classified into the same group based on those qualities. The other options don't make a lot of sense - they don't refer to a specific group of people.
