Which of the following is true for operator precedence parsing?

Which of the following is true for operator precedence parsing? Correct Answer For all pair of non-terminal

There are two important properties for these operator precedence parsers is that it does not appear on the right side of any production and no production has two adjacent non-terminals. Implying that no production right side is empty or has two adjacent non-terminals. So accordingly to property option (A) is correct.

Consider the grammar given below E? E+E | E*E | E-E | E/E | E^E | (E) | id Assume that + and ^ have the same but least precedence, * and / have the next higher precedence but the same precedence and finally ^ has the highest precedence. Assume + and ^ associate to the left like * and / and that ^ associates to the right. Choose the correct for the ordered pairs (^,^), (-,-), (+,+), (*,*) in the operator precedence table constructed for the grammar.
