Q. Consider the CFG with {S,A,B) as the non-terminal alphabet, {a,b) as the terminal alphabet, S as the start symbol and the following set of production rules
S --> aB S --> bA
B --> b A --> a
B --> bS A --> aS
B --> aBB A --> bAA
Which of the following strings is generated by the grammar?

• (A) aaaabb
• (B) aabbbb
• (C) aabbab
• (D) abbbba
