Question 7 When using the pumping lemma with length to prove that the language L = {ba"b, n>0} is nonregular, the following approach is taken. Assume L is regular. Then there exists an FA with k states which accepts L. We choose a word w = bakb = xyz, which is a word in L. Some options for choosing xyz exist. A. X = 4, y = b, z = akb B. x = b, y = a, z = ak-pb, for some p > 0, p
