Which statement best describes how Mr. Utterson’s view of civility and proper behavior changes throughout The Strange Case of Dr. Jekyll and Mr. Hyde ?

At first, Utterson is restrained and respects his friends’ privacy, even when he is worried about Jekyll. As the mystery deepens, he sets aside those polite limits: he investigates Hyde and eventually helps Poole break into Jekyll’s cabinet. This shows he becomes less concerned with manners and invades his friend’s privacy to find answers, so D is correct.
