A generational cohort is a group of people who

A) purchase only one brand of a product throughout their lifetime.
B) grew up and went to school together.
C) have the same beliefs and values as the generation that came before them.
D) have similar purchase behaviors because they have shared the same stage of life.
E) are not open to new things.

A generational cohort refers to a group of individuals born and raised during the same period, who share similar life experiences, values, and attitudes, including their purchase behaviors. As such, they are likely to respond to marketing messages and products in a similar way based on their collective life stage. Therefore, choice D, which implies shared purchase behaviors due to shared life experiences, is the best answer.
