22. The key difference between a left-most and a right-most derivation is that result (in function myf2): read/write access A. left-most derivations always start with the starting rule (or at the root of the tree) while right most derivations always start with the input string and work their way up to the starting rule (or start at the leaves and work towards the root) B. Left-most derivations are generators and right-most derivations are recognizers. Given a sentential form that contains multiple non-terminals, a left-most derivation always picks the left-most non-terminal to reduce next, while a right-most derivation always picks the right- most non-terminal to reduce next. C. A right-most derivation uses the handle-pruning technique to derive a sentence, while a left- most derivation uses the left-recursive technique to derive a sentence. D
