I do agree with the other user. Looking at the answers, A for the 1st, and B for the second make the most sense by far.
One difference is in the book the characters soda and sandy were heavily involved, while in the movie soda and sandys relationship is mentioned maybe once. Also in the movie it shows the brothers parents being vividly killed in a car and train crash while in the book it is just said to be an auto accident. In the movie Dally robs a store and gets hurt, while in the novel he robs the store over the phone.
I’m pretty sure it’s c but I don’t really know so !
