Therefore correct option is C
Step-by-step explanation:
The unique aspect of the population of institutions of higher education is c. it changes from day to day, semester to semester, and year to year. This dynamic nature is characterized by the continuous influx of new students and the graduation of others, leading to a demographic that is constantly evolving. Contrary to some perceptions, the population of colleges and universities is not limited to a narrow age range of young adults. While traditionally it consisted primarily of individuals immediately out of high school, today's higher education population includes adults returning to school, career changers, and international students, contributing to a diverse and shifting demographic.
As the demographics in higher education institutions change, so do the effects on socialization, politics, and economic factors. For instance, the ways students engage with political activities can vary widely, despite the critical role they can play in facilitating political change.
