B) Would be the best of the choices given in ny opinion. Because the only other one that i thought of was A but physical fitness is not a planned event ect
Here is my strategy,
Try to convince the community to eat vegetables in every meal. They should at least have salad placed next to their meal. After each meal, tell them that they should consume fruit such as banana. And if they feel hungry, just tell them to eat fruits.
Hope this helps
