Answer:
B. The strength, endurance, and flexibility to meet the demands of daily living.
Explanation:
The question states that Miranda is physically fit. Using common sense we can see that she will be strong and capable of meeting the demands of daily living, as that is essentially the definition of being physically fit. There is no evidence to suggest an increased risk of osteoporosis (no family history or explained lack of calcium in the diet), and there is no reason that Miranda would have a greater need for vitamins (no low vitamin levels mentioned) because she's healthy. The question said she is healthy, and the answer is- she's healthy.
