Choose the most suitable option to replace the highlighted part of the sentence: The doctor advised him to stop consuming junk food and doing workouts regularly.

The correct substitution ofthe highlighted words is (c)to stop consuming junk food and to work out regularly. The verb advised followed by an object ( him) correctly takes the to-infinitive form. Additionally, the two coordinated actions joined by and must be grammatically parallel. Option (c) maintains parallelism by using to + base verb in both parts. Corrected sentence: The doctor advised him to stop consuming junk food and to work out regularly. Grammatical rules applied: • Verb + object + to-infinitive is standard after advise. • Parallelism: elements joined by and must have the same grammatical form. Example: She advised him to reduce stress and to exercise daily. Why other options are incorrect: • (a) stopping junk food and doing regular workouts: breaks the required to-infinitive structure after advised him. • (b) to stop junk food and to workouts regularly: incorrect verb form ( workouts used as a verb). • (d) to not consume junk food and do workouts: lacks parallelism ( to not consume vs do), and do workouts is less idiomatic than work out.
