Correct Answer: Father said to the mechanic, “How much have I to pay for the repairs?”

Solution : The correct choice is the fourth option .

Narration Conversion:

• The verb asked is changed to said in direct speech, as the words are directly quoted.
• The third-person pronoun he becomes the first-person pronoun I, as the perspective shifts back to the father.
• The simple past tense (had) is changed to the simple present tense (have) .
• The words of the speaker are enclosed in quotation marks.

Therefore, the sentence in the direct form is: Father said to the mechanic, 'How much have I to pay for the repairs?'
