Given its themes, which of William Blake's books is more likely to include the poem “The Poison Tree”?

“The Poison Tree” is more likely to be found in Songs of Experience. This poem explores themes of anger, deceit, and the consequences of suppressed feelings, which align more closely with the themes of experience and the darker aspects of human emotions presented in that collection. In contrast, Songs of Innocence focuses on themes of childhood, purity, and innocence.
