For a context-free grammar, FOLLOW(A) is the set of terminals that can appear immediately to the right of non-terminal A in some “sentential” form. We defined to sets LFOLLOW(A) and RFOLLOW(A) by replacing the word “left most sentential” and “right most sentential” respectively in the definition of FOLLOW(A).
Which of the following statements is/are tru
  • a)
    FOLLOW(A) and RFOLLOW(A) may be different.
  • b)
    FOLLOW(A) and RFOLLOW(A) are always the same.
  • c)
    All the three sets are identical.
  • d)
    All the three sets are different.
Correct answer is option 'C'. Can you explain this answer?

Definition of Follow (A) as per question “The set of terminals that can appears immediately to the right of non-terminal A in same sentential form”. If the above definition is changed to replace “ sentential” with “ left-most sentential” for L FOLLOW (A) and “right-most sentential” for R FOLLOW (A)
We are still considering the terminal symbol to the right of A ’ .
Hence all three sets would be identical
