The correct answer is A. I asked the boy if he would step with me into the garden.
The sentence “I said to the boy, ‘Will you step with me into the garden?'” is an example of a direct question. A direct question is a question that is asked in a way that requires a specific answer. In this case, the speaker is asking the boy if he would like to step with him into the garden.
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option B, “I said to the boy if he would step with me in the garden,” is a statement, not a question. Option C, “I said to the boy if he would like to step with me in the garden,” is a question, but it is not a direct question. Option D, “I requested the boy to step with me in the garden,” is a request, not a question.
