Answer:
B) His efforts to heal render him earnest and genuine.
Step-by-step explanation:
The excerpt shows that the speaker is nervous, anxious and apprehensive, so he begins to do random things in an attempt to calm down and take his thoughts away from what is making him nervous. The speaker's efforts to calm down make him sincere and genuine and this makes the reader identify with and feel represented in the work, as readers are likely to have gone through similar situations and sought to do the same trivial things to calm down.
