Which of the following statements is/are correct? I. The language L accepts all the strings of a's and b's where the third symbol from left end is b. The regular expression for L is (a+b)² b(a+b)*. II. The language L accepts all the strings of a's and b's where the number of a's in a string is divisible by 3. The regular expression for L is (b* ab* ab* ab*)* . III. The regular expression R=(a+b)". The number of states required to construct the minimal DFA for the regular expression R is n+2. (A) I and II (B) I and III (C) II and III (D) All are correct
