D. Radio Button A balanced diet and exercise

The correct answer is D, a balanced diet and exercise. To determine this, let's analyze each option:

A. A balanced diet and watching TV: Watching TV is not a factor that directly contributes to physical health. While a balanced diet is important, exercise is also needed for overall health.

B. A diet high in sweets and going swimming: A diet high in sweets is not healthy and can lead to various health issues. Going swimming can be a form of exercise, but a healthy diet is crucial for maintaining overall health.

C. Eating lots of fruit and vegetables and playing computer games: Eating lots of fruits and vegetables is indeed healthy for the body. However, playing computer games does not contribute to physical health.

D. A balanced diet and exercise: This option correctly identifies two crucial factors for maintaining good health. A balanced diet provides the necessary nutrients, while exercise helps keep our bodies fit and strong.

Therefore, option D, a balanced diet and exercise, is the correct answer for keeping us healthy.
