The other options are incorrect because they do not accurately reflect the content of the question. Option A is incorrect because it does not mention that the voice was close behind the speaker. Option B is incorrect because it does not mention that the voice was soft. Option C is incorrect because it does not mention that the voice was from the speaker’s back.

The question is about a soft voice that asks the speaker if they are alone. The voice is close behind the speaker, and it is soft. This suggests that the voice is coming from someone who is trying to be discreet. The speaker is not sure who the voice is, but they are aware that they are not alone.
