u/One-Bench-9676

Is there a way of interpreting this so that the answer selected is not also correct? The top right is from the class notes the professor posted. I feel like I’m not bad at this but had classmates agreeing that was incorrect. Astro and Opus 5.5 also could not come up with a reason for that answer to be incorrect (I’m not saying this makes me right). Thanks for any help.
