Which of the following is the main internal conflict suffered by the protagonist of "The Moment Before the Gun Went Off"?

He is sad for the death of the young boy, but believes his white-man privileges are legitimate.
He will be condemned for the premeditated murder, but the shooting was an accident.
He killed his own son, but no one in the black or white community will believe him.
He never spoke against apartheid, but inside he believes it is inhuman.

I'm pretty sure the answer is D, I just need some confirmation. Thanks!
