Answer Details

The best option to complete the sentence is "had to rise". The phrase "when I was in school" indicates that the sentence is referring to a past event, and the word "boarders" suggests that this is a boarding school. The phrase "very early every morning" suggests that the boarders had to wake up at a specific time. The phrase "had to rise" is in the past tense, and it means that the boarders were required to wake up early in the morning during the time when the speaker was in school. This is the most appropriate option because it refers to a specific past event and is in the correct tense.
