Chomsky normal form (CNF) is a normal form for context-free grammars.

Chomsky normal form (CNF) is a normal form for context-free grammars. Select all of the following statements that are true. For every regular language there exists a context-free grammar in CNF that generates the language. Every context-free grammar is in CNF A rule of the form R + aB is a valid rule in CNF. Every grammar expressed in CNF is unambiguous. For every context-free grammar G there exists a grammar H in CNF such that L(G) = L(H)
