A person with type 1 diabetes is planning a morning of conservation work. The table shows four possible plans.
For each plan, the person would start with the same blood glucose concentration and take the same dose of insulin immediately before eating.
| plan | carbohydrate eaten in the meal in g | time spent doing the same strenuous task in min |
|---|---|---|
| A | 60 | 30 |
| B | 60 | 90 |
| C | 30 | 30 |
| D | 30 | 90 |
State which plan has the greatest risk of causing the person's blood glucose concentration to fall too low.
Explain why the plan you identified has the greatest risk of causing the person's blood glucose concentration to fall too low.
