Read the following pairs: Active Voice: I. They laughed at his warnings and objected to all his proposals. II. Do not insult the weak. Passive Voice: I. His warnings were laughed at and his proposals were objected to. II. You are advised to not insult the weak. Identify the pair(s) wherein the Passive Voice is correctly stated.

In pair I, the passive voice is correctly formed: 'His warnings were laughed at and his proposals were objected to.' This is the standard passive transformation of the active sentence with phrasal verbs. In pair II, the active 'Do not insult the weak' is an imperative sentence. Its correct passive should be 'Let the weak not be insulted' or 'You are advised not to insult the weak' (note: 'advised not to insult' is correct; 'advised to not insult' is a split infinitive and considered grammatically less acceptable). Therefore, only pair I is correctly stated in passive voice.
