Step-by-step explanation:
The correct answer to the question is D. culture.
In middle adulthood, there are three aspects of the contexts of life that influence development. These aspects are historical, gender, and genetic. However, culture is not one of the three aspects.
For example, historical context refers to the events and circumstances that occur during a person's lifetime and can shape their development. Gender also plays a role as societal expectations and norms associated with gender can influence the opportunities and experiences individuals have during middle adulthood.
