Concept:When converting indirect speech to direct speech, the exact words of the speaker are quoted. Exhortations or commands become imperative sentences in direct speech.
Rule / Clue:The indirect verb "exhorted ... to fight ... never to think" shows a strong command. In direct speech, imperative sentences use the base verb and often need an exclamation mark for urgency.
Explanation:The original sentence reports the commander's command indirectly.
Option A uses "You should fight" which is a suggestion, not a direct command.
Option B uses "Let us fight" which includes the speaker, changing the meaning.
Option C uses the imperative "Fight" and "Never think" with exclamation marks, correctly matching the command and urgency.
Option D changes the order, but the key is the imperative form; however, it places "Don't ever think" first, which alters the emphasis.
Therefore, option C is the accurate direct speech version.
Answer:The commander said to the men, "Fight to the last breath! Never think of surrender!" (Option C)
