A bank sends offers for private student loans to recent high school graduates.

Psychographic segmentation involves categorizing consumers based on their lifestyle, values, interests, or personality traits. In this case, the bank is not focusing on the graduates' psychographic characteristics but rather on their demographic status as recent high school graduates, which does not align with psychographic criteria.

Geographic segmentation divides the market based on location, such as countries, regions, or cities. The bank's marketing strategy does not depend on the geographical location of the graduates; instead, it is concerned with their educational status, making this choice incorrect.

Product-related segmentation focuses on the relationship between consumers and a specific product, such as usage rates or brand loyalty. The bank's strategy is centered around targeting a specific demographic group rather than their relationship with a product, hence this option does not apply.
