option [A]--LHS must be exactly 1 Non-terminal , RHS can be any String of terminals and Non--Terminals.

Option (A) is correct.In formal language theory, a context-free grammar (CFG) is a formal grammar in which every production rule is of the formV → wwhere V is a single nonterminal symbol, and w is a string of terminals and/or nonterminals (w can be empty).

B. |
A parsing algorithm which performs a left to right scanning and a right most deviation is RL (1).
|
C. | LR parser is Bottom - Up parser. |
D. | In LL(1), the 1 indicates that there is a one - symbol look - ahead. |

Option(B) is correct.Reason:1.LR and LALr parser are Bottom-Up parser2. In LL(1), 1->indicates one-symbol look ahead.Therefore (B) is false.
