If a finite state machine transitions according to Kleene's theorem, which outcome concerning the set of recognizable languages results?

💡 Explanation

Kleene's theorem ensures that regular languages remain regular under union, concatenation, and Kleene star; because the finite state machine operations correspond to these set operations, the recognizable languages remain regular. Therefore, set operations preserve regularity, rather than destroying it, because Kleene's theorem is specifically designed to guarantee this.
