Consider the grammar S ? (S) | a Let the number of states in SLR(1), LR(1) and LALR(1) parsers for the grammar be n₁, n₂ and n₃ respectively. The following relationship holds good A) n₁ < n₂ < n₃ B) n₁ = n₃ < n₂ C) n₁ = n₂ = n₃ D) n₁ ? n₃ ? n₂

LR(1) parsers typically have more states than SLR(1) and LALR(1) parsers because they are more powerful and can handle more complex grammars by considering more lookahead information. LALR(1) parsers merge some of the states that are distinct in LR(1) parsers, leading to a smaller number of states than LR(1) but typically the same number as SLR(1) for many grammars.
