please select the best answer from the choices provided.

Explanation:

To improve body composition and reduce BMI, the FITT principles (Frequency, Intensity, Time, Type) should be applied. Option A: Adding cardiovascular and weight training (diversifying type) and eating low - calorie meals (supporting calorie deficit for fat loss) aligns with FITT. Option B: High - calorie diet and increasing swimming to 5 days may not help reduce BMI as high calories can counteract fat loss. Option C: 4,000 calories a day is too high for fat loss. Option D: A very restrictive diet (high - protein, low - carbohydrate) and 5 days of weight training may not be balanced, and the diet approach is not the best for long - term BMI reduction compared to A.

Answer:

A. She should add more cardiovascular training and weight training to her exercise routine and eat several low - calorie meals throughout the day.
