What does the Pumping lemma for regular languages say? Select one: O Every "long enough" word in language L can be written in the form uv'w. O If a language L contains a "long enough" word z=uvw, then L contains infinitely many words of the form uv w. O Every word that can be written with a regular expression, can be also "pumped". O For an arbitrary word z=uvw in language L, there exist infinitely many words of the form uv'w, that are also in L.
