Correct Answer:
B. He swore that he did not know his name.
This question tests your ability to convert direct speech into indirect speech, also known as narration change. The phrase "By God" indicates an oath, which is best conveyed by the verb "swore" in indirect speech. The pronoun "I" changes to "he" to reflect the speaker, and the present tense "do not know" shifts to the past tense "did not know" in indirect speech. The object "his name" remains unchanged.
- Option B: "He swore that he did not know his name." is correct because it accurately transforms the oath, pronoun, and verb tense.
- Option A: "He said that by God..." is incorrect as it doesn't properly convert the oath into an appropriate verb.
- Option C: "He swore that he did not know my name." is incorrect because it changes "his name" to "my name," altering the original meaning.
