Identify the correct reported form of the given sentence:
Ravi said to his friend, "work hard".

Correct option is C

Solution: Correct Answer: (c) Ravi advised his friend to work hard.
Explanation:
The sentence "Ravi said to his friend, 'Work hard'" is a command or piece of advice.
When we convert such sentences into indirect (reported) speech, we use reporting verbs like advise, suggest, tell, order, request, etc. depending on the tone of the sentence.
Here, “Work hard” is not an order but a piece of advice, so we use the reporting verb “advised.”
The structure becomes:
→Ravi advised his friend to work hard.
Information Booster:
→Imperative sentences (those that give orders, advice, requests, or instructions) are changed into indirect speech using to + verb (infinitive form).
Example:
He said to me, “Study well.” → He advised me to study well.
Reporting verbs you can use:
advised → for suggestions or moral guidance
ordered/commanded → for strict instructions
requested → for polite requests
Additional Knowledge:
‘Said to’ changes according to meaning:
said to → told/asked/advised/ordered etc.
→No comma or quotation marks remain in reported speech.
→Verb changes: The reporting verb usually stays in past tense, but the infinitive verb (to work) remains unchanged.
