What common theme is found in sentimental novels?

Sentimental novels often emphasize emotional connections and the depth of feelings experienced by characters, particularly in the context of love. In these stories, emotional bonds are prioritized over physical relationships, showcasing how love can affect individuals profoundly. The focus tends to be on the inner experiences of characters, their struggles with emotions, and how these shape their lives. This emphasis on emotional love allows readers to connect with the characters on a deeper level, often highlighting themes of compassion, empathy, and moral growth.

While the other choices touch on different elements that might be present in various genres or narratives, they do not capture the essence of sentimental novels as effectively as the exploration of emotional love does. Wealth accumulation, supernatural events, and adventure may feature in a range of literary works, but they do not represent the core thematic focus that defines sentimental literature.
