Final answer:
The least likely example of age discrimination is option B, where a modeling agency objects to a 52-year-old modelling for a teen product line, as it pertains to target marketing rather than discrimination.
Step-by-step explanation:
The example that would most likely NOT be considered evidence of age discrimination is option B: A modeling agency has sent a 52-year-old man to pose for a photo shoot for a teen-oriented product line. The shoot director was overheard saying on the phone, "What were you thinking? I gave you our target customer profile!" This situation does not directly reflect age discrimination but rather a mismatch between the model's age and the targeted consumer age group for the product, which is a legitimate marketing concern.
Age discrimination typically refers to situations where an individual is treated less favorably because of their age without any legitimate business reason. With this in mind, the other examples (A, C, and D) all imply a bias against older individuals based on stereotypes or policies that unfairly target them due to their age.
