Explanation:

The Nazca Plate and the South American Plate interact at a convergent boundary. At convergent boundaries, oceanic plates (like Nazca) and continental plates (like South American) push toward each other, with the oceanic plate usually subducting. The option "Plates are pushing toward each other" matches this convergent interaction. "Plates are spreading apart" is for divergent boundaries, and "Plates are sliding past each other" is for transform boundaries.

Answer:

Plates are pushing toward each other.
