Answer
Brief Explanations:
A gerund is a verb - ing form that functions as a noun. In "A healthy lifestyle requires getting regular exercise", "getting regular exercise" acts as the object of the verb "requires". In "Watching too much television may contribute to depression", "Watching too much television" acts as the subject of the sentence. The other underlined phrases are not gerund phrases. "To live a long life" is an infinitive phrase, "by nature" is a prepositional phrase, and "to stay calm under pressure" is an infinitive phrase modifying "ability".
Answer:
A. A healthy lifestyle requires getting regular exercise. C. Watching too much television may contribute to depression.
