The correct answer is B. An executive belongs to a different class than her parents.
Explanation:
In sociology, the term "intragenerational mobility" is used when individuals change the economic status or social class, either by improving it or dimish it mainly due to changes in society and in reference to the economic status held by previous generations including parents, grandparents, etc. This means, in intragenerational mobility individuals have a higher or lower economical status than previous generations, which is common in societies due to the change they undergo. Considering this, the scenario that is an example of intragenerational mobility is "An executive belongs to a different class than her parents", because in this case one individual (the executive) has a different economic status or belongs to a different social class than previous generations, which is the basic principle of intragenerational mobility.
