The most accurate response to whether Marni's situation is an example of absolute deprivation is:
No, Marni’s needs are completely met.
While Marni is facing significant challenges and does not have a stable living situation, she is managing to fulfill her basic needs for shelter (albeit in her car), food (from her job), and hygiene (using the gym showers). Absolute deprivation typically refers to a state where basic needs for survival—such as food, water, shelter, and safety—are not met at all. In Marni's case, although her circumstances are difficult, her basic needs are still being addressed to some extent.
