Key Points

Complete Sentence: "The doctor advised him to avoid eating sweets and to exercise regularly."

Additional Information
- Option 1: "avoiding sweets and doing regular exercise" is incorrect because it uses "avoiding" instead of "to avoid," breaking the parallel structure.
- Option 2: "to avoid sweets and to exercises regularly" is incorrect as "to exercises" is grammatically wrong (the correct form is "to exercise").
- Option 4: "to not eat sweets and do exercises" is incorrect as it does not maintain proper parallel structure and uses "do exercises" instead of "to exercise."
