It is important that physical activity is part of the lives of children, adults and the elderly. Exercise doesn't have to be energetic: you can find ways to stay active that fit your daily routine, such as walking. If you never exercised or haven't done it in a while, it's easy to start. Physical activity is essential to maintain a healthy body weight and is even beneficial during pregnancy.

Eating the right nutrients provides the fuel you need to exercise and drink fluids helps prevent dehydration.

I'd say D because it is always good to have a goal for that, and if you plan it out, you have a better chance of reaching it.
