Which of the following is a common theme found in literature?

Love, conflict, or redemption are indeed considered common themes in literature because they reflect universal human experiences and emotions that resonate with readers across different cultures and time periods. These themes often drive the narrative and character interactions, allowing readers to engage with the story on a deeper emotional level.

For instance, love can motivate characters' actions and decisions, conflict can create tension and propel the plot forward, and redemption can offer a transformative arc for characters, highlighting moral or personal growth. These themes can be explored in various ways through different genres, illustrating the complexity of human relationships and struggles.

The other options focus on elements of storytelling and style rather than themes. Setting and time establish the backdrop but do not convey deeper human experiences. Character and plot development describe the structural components of a story, while writing style pertains to the author's technique and choice of language rather than the themes being explored. Thus, while all options play significant roles in literature, love, conflict, or redemption stand out as themes that drive the emotional and thematic core of literary works.
