Correct Answer: I said to carpenter, “How long will you take to polish my furniture?”

Solution : The second option is correct.

Explanation:
Direct speech, also known as quoted speech or direct discourse, refers to the representation of someone's words or statements exactly as they were spoken.
Narration conversion:

• If the indirect part of the sentence uses ' asked ' as a reporting verb, then a " question mark " should be added in the direct speech part.
• The reporting verb "asked" changes to "said to".
• The modal "would" changes to "will" to show the direct speech part.
• The third person pronoun "he" changes to the second person pronoun "you".
• The direct words of the speaker are enclosed in inverted commas.

Therefore, the direct form would be: I said to carpenter, "How long will you take to polish my furniture? "
