Base on the given choices, Isabel is a voluntary temporary as this is where a person has a thought of delaying to be married or to get married because of their will of wanting to pursue their careers or education which we could see from Isabel’s thoughts of not entertaining marriage because of education as she wants pursue her law studies for two years. Voluntary stable is not the right choice for it is a way of explaining couples of having a single lifestyle. The involuntary temporary in the other hand, is where a single individual is looking for a partner though there is no suitable to his or her standards and lastly involuntary stable is also wrong for it is where couples have the desires of being single but there is no guarantee that they are willing to do it.
