Answer:
OB. helps the speaker remember his words more vividly.
Step-by-step explanation:
In the given passage, the narrator/ speaker admits how he would never live up to his father's expectations. Moreover, he also believes that his father would never be satisfied with the way he is living his life.
But most of all, he clearly remembers the words of his father- "Waste of time in your prime is a crime, my boy!" which always becomes a reminder of how "aimless" his life is/ felt like. And this echo of words became more like an alarm ringtone. The rhyme of words such as "time, prime, crime" presents a vivid memory in the boy, making it more ingrained in his consciousness.
Thus, the correct answer is that the rhyme helps the speaker remember his father's words more vividly.
