Consider the productions S→ AB , S→YZ, each non-terminal S, A, B, Y
and Z has two attributes: s is a synthesized
attribute and i is an inherited attribute. Consider the following semantic rules:

Rule 1 : A.i = S.i + 2 , B.i = A.i + S.i ,
S.s = A.s + B.s

Rule 2: Y.i = S.i + Z.s , Z.i = S.i + Y.s Which one of the following is TRUE?
