Final answer:
Donating to an environment protection organization best exemplifies the utilitarian function of attitudes as it likely brings personal satisfaction and aligns with the aim of maximizing happiness for many.
Step-by-step explanation:
The utilitarian function of attitudes refers to how attitudes can lead to behaviors that maximize personal satisfaction and happiness. When considering the options provided, the one that best exemplifies this utilitarian function is a person donating to an environment protection organization. This action likely provides the individual with a sense of personal satisfaction from contributing to a cause that benefits the greater good, aligning with the principle of creating the greatest amount of happiness for the greatest number of people.
This concept is related to the law of diminishing marginal utility, which states that while the first units of a good consumed provide significant satisfaction, the utility gained from subsequent units tends to decline. The chosen action of donating to an environmental organization likely sustains its utility over time, as the person perceives ongoing benefits to society from their contribution.
