Although many biologists believed that the invasive vine *Pueraria lobata* (kudzu) spreads solely through vegetative cloning, recent genetic analysis has revealed a more complex reproductive strategy. Researcher Dr. Maya Lin conducted a study analyzing kudzu populations across three southeastern states. Lin's team discovered high levels of genetic diversity within individual forest patches, a characteristic typical of sexual reproduction rather than clonal propagation. Additionally, they identified mature seed pods containing viable seeds that had successfully germinated under controlled greenhouse conditions. These findings suggest that seed dispersal plays a significant role in kudzu's rapid expansion, challenging the long-held assumption that the plant relies exclusively on cloning.
Which choice best describes the overall structure of the text?

- BIt presents a solution to an ecological problem, details the steps taken to implement the solution, and evaluates the final outcomes.
- CIt argues in favor of a traditional theory, analyzes the reasons why that theory has persisted, and highlights a minor detail from a recent study.
- DIt outlines a researcher's biography, explains the methodology of her greenhouse experiments, and lists the specific locations of kudzu forests.
