What can the reader most likely conclude about byron's point of view

The complete question includes a quote and the following choices:
(from "The Watsons go to Birmingham - 1963") “Today is the day you check out of the World-Famous Watson Pet Hospital. Don’t let me catch you back there no more. You ain’t got no cause to be ashamed or scared or nothing. You smart enough to figure this one out yourself."            
A- He is sad about Kenny’s behaviour. B- He wants Kenny to confront his fears. C- He is confused that Kenny is so upset. D- He believes Kenny needs to see a counsellor

The correct answer is B. Byron doesn't seem sad, nor truly confused about Kenny's behaviour; it is more likely he is forcing Kenny to go to the hospital for his own good sake, he should have no reason to be scared or ashamed.
