<u><em>Answer:</em></u>
A. The speaker is up late at night reading and hears a knocking sound.
<em><u>Explanation:</u></em>
The Scene the question refers to is from <em>The Raven</em> by Edgar Allan Poe:
<em>Once upon a midnight dreary, while I pondered, weak and weary,
</em>
<em>Over many a quaint and curious volume of forgotten lore-
</em>
<em>While I nodded, nearly napping, suddenly there came a tapping,
</em>
<em>As of someone gently rapping, rapping at my chamber door.
</em>
<em>"'Tis some visitor," I muttered, "tapping at my chamber door-
</em>
<em>Only this and nothing more."</em>
