The correct answer is X generational cohort.
Step-by-step explanation:
Generational cohorts refer to the grouping of social generations that are formed by people who were born in the same time of period, share common features and have similar behaviors, beliefs, and attitudes. According to this, different generations including the silent generation, the baby boomers, the generation x and the millennials have been proposed to describe the way in which people born in certain periods are similar in certain ways.
In the case of the Generation X, this covers the people that were between the 60s and the 70s during the historical period in which market was growing, because of this, people that belong to this generation are good at aspects related to the market such as buying or understanding and analyzing advertisements as they have been exposed to them during all their lives. Also, people from this generation is not interested in following the trends but just finding some balance in their lives.
