The grammar whose productions are → if id then → if id then else → id := id is ambiguous because a) the sentence if a then if b then c:= d has two parse trees b) the left most and right most derivations of the sentence if a then if b then c:= d give rise to different parse trees c) the sentence if a then if b then c:= d else c:= f has more than two parse trees d) the sentence if a then if b then c:= d else c:= f has two parse trees

Correct Answer: d
