PLZ, I need help! thx!

[13] Took me until I was a sophomore in high school — yes, that long — before I finally found it in me to start facing my terror. By then, my older brother was in remission and wearing a wig to hide his baldness. Maybe his improbable survival was what gave me courage, or maybe it was all the Robert Cormier I was reading — his young heroes were always asking themselves, ‘‘Do I dare disturb the universe?’’ before ultimately deciding that yes, they did dare. Whatever it was, one day I found myself
fleeing from a sighting of the brothers, and suddenly I was brought up short by an appalling vision: me running away forever.

What inspired Diaz to stop running away? (Paragraph 13)
A. learning from his brother how to fight back
B. knowing he is equally matched to fight the brothers
C. reading a book about how to get even with enemies
D. reading stories of others who courageously faced frightening things
