The right option that fills the blank in the paragraph is:

- Isabel Allende y Octavio Paz usaban las imágenes de los fantasmas en sus novelas para traer un elemento extraño a sus obras.

Explanation:

Isabel Allende, the renowned Chilean writer nationalized in the US and Octavio Paz, the Mexican poet, literature Nobel in 1990, have a tendency to add ghosts and other supernatural beings into their literary productions, first Isabel Allende, in her first work "la casa de los espíritus" being faithful to the magical realism that it represents, by narrating together with the story of a family that arrives in Chile, a certain connection with ghosts and supernatural things that remind a little of the work of Gabriel García Márquez "cien años de soledad", Octavio Paz by his part was always a lover of esotericism and the intangibility of things, although his poems reflect them on certain occasions, the work that can best determine this inclusion of ghosts is "topoems" of 1971.
