(D): Not joining FFA and joining HOSA instead.
My best advice to Janice is to choose one over the other by joining HOSA instead of FFA or choose to use both. If her idea is to choose Medicine over farming, then HOSA is the way to go. HOSA is an available component that prepares students for a health career path and offer programs in health occupations and health sciences. It helps its members build self-confidence; develop effective leadership and strengthen their technical and academic skills.
However, as mentioned before, she can decide to use her background in farming while learning more about medicine. This will act as an advantage since she can have a strong understanding in medicinal farming. Example, she can learn ways to create effective drugs from plants.
