Answer:
D. The old man prepares for his own murder.
Explanation:
According to the question, Karishma is reading "The Tell-Tale Heart." and she reads an excerpt, looks for clues, then makes a prediction about what happens next.
According to her first prediction, she believes that the narrator would carry out the murder plot undetected because his approach to the house has been stealthy so far and no one has heard him.
Next, from the subsequent excerpt she reads, the old man hears him as he is about to open the door and asks loudly who is there.
Therefore, the revision that is most logical for Karishma to make to her prediction as she continues to read is that the old man prepares for his own murder.
This is because, he already knows there is an intruder and now he would prepare for his murder.
