Final answer:
Sergeant Major Morris's reaction to discussing the three wishes he made with the monkey's paw suggests fright or distress, leading us to infer that the monkey's paw is a cursed object.
Step-by-step explanation:
When Sergeant Major Morris's face whitens as he talks about his experiences with the paw and its three wishes, it suggests a deep-seated fear or alarm. The fact that his face turns pale is a classic symbol of horror or distress, indicating that the paw has a dark or malevolent nature. Considering this reaction and the context of the story "The Monkey's Paw" by W.W. Jacobs, we can infer that the paw is a cursed object. Hence, out of the given options, the most accurate inference we can make about the paw would be A. It is a cursed object. The paw certainly does not grant unlimited wishes, as it is limited to three, and there's nothing explicitly suggesting that it only grants evil wishes. The overarching theme of the story is that interference with fate carries dire consequences, often translated as bad luck; therefore, the paw could be commonly associated with bringing bad luck, but the phrasing of option A is more fitting to the narrative presented.
