Step-by-step explanation:
The exercise plan that the patient understands is option d. "I will take a brisk 30-minute walk 5 days per week and do resistance training 3 times a week." This plan includes a combination of aerobic exercise (brisk walk) and strength training (resistance training), which are recommended for individuals with type 2 diabetes. Aerobic exercise helps to improve insulin sensitivity and lower blood glucose levels, while strength training helps to build muscle mass and increase basal metabolic rate.
