B). Generative as mentors in the workplace, community volunteers, or in family relationships.

Explanation:

The childless middle-aged adults could be 'generative as mentors in the workplace, community volunteers, or in family relationships' as they are presumed to be fair or unbiased while mentoring due to the inner emptiness and absence of social support faced by them(that enforces them to fair in order to look for satisfaction).

Such people often end up in depression and solitude due to the lack of social support that a child offers to a person. Thus, they would be fairer as it would assist them to overcome the grief and avoid the negative influence of childlessness on their psychological health. Hence, option B is the correct answer.
