The best that describes the symbolism used in this passage is option A. the portfolio symbolizes Clarence’s hopes and hard work.
Clarence realizes that he won’t be able to arrive on time at the interview so when he looks at the portfolio he sees his dreams of getting the job fade away as he believes it’s difficult that the company will reschedule the appointment.
Option B is incorrect since the focus is on Clarence not being able to arrive to the interview.
Option D is also incorrect as Clarence brings the memories of his father as a happy one, since he learnt from his father.
