Answer:
c. Senior citizens (65 years and older) - psychographic
Explanation:
This is the sentence that is not correct. Demographic information usually focuses on the external factors of a person. These include age, ethnicity, gender, or location. On the other hand, psychographic information tends to focus on more personal and unique characteristics, such as a person's motivations, beliefs or values. Both of these approaches are useful when approaching the process of segmenting.
