Answer:
Step-by-step explanation:
I think your best answer would be C, but D is a good answer as well. this is poetry and it cannot be nailed down by ABC or D. A good case could be made for all the answers, except maybe A.
B for example shows how hypocritical the teller can be. While he smiles and smiles underneath there are the tears of wrath which grows and grows because he does nothing to correct his anger.
D is also true. He does nothing to correct his attitude and so his wrath grows.
C I like C because his lack of courage in speaking up leads him to a place where only anger can grow. The problem is that what he is developing is wrath not anger. There is a difference. Wrath has hatred in it.
I'm going to stick with C, but D is also possible.
