Consider the language of odd-length palindromes with a special center symbo 'c', L = {xcxR: x is in (a+b)+ and xR is just the reverse of x}. One example is the string "baacaab". What can be said about a PDA for deciding L? O A. We can build a deterministic PDA for L with just the stack alphabet r = {Z, A }. OB. We can build a deterministic PDA for L with just the stack alphabet r = {Z, A, B }. O C. We need a nondeterministic PDA for L, with just the stack alphabet r = {Z, A }. D. We need a nondeterministic PDA for L, with just the stack alphabet = {Z, A, B}.
