Which of the following best describes ageism?

Ageism is best described as the stereotyping of individuals based on their age. This concept encapsulates the prejudices and discriminatory practices that arise from assumptions about a person's capabilities, preferences, or value based solely on how old they are. It can manifest in various areas, including the workplace, healthcare, and social interactions, where older or younger individuals may be unfairly treated or judged based on their age rather than their actual abilities or experiences.

The other options focus on broader themes related to employment and diversity, which, while important, do not capture the essence of ageism specifically. Focusing on equal employment opportunities and promoting workplace diversity are essential for creating inclusive environments but are not defining characteristics of ageism itself. Reducing age-related biases is a goal that can emerge from addressing ageism but does not define what ageism is. Thus, the choice of stereotyping based on age accurately reflects the core issue of ageism.
