Correct Answer:
C. Smith
The statement 'Curriculum presents instructional material' is attributed to Smith (specifically B. Othanel Smith). Smith defined curriculum as a sequence of potential experiences set up in the school for the purpose of disciplining children and youth in group ways of thinking and acting, which inherently involves presenting instructional material. While other theorists like Jack Kerr also contributed significantly to curriculum theory, this particular phrasing aligns with Smith's perspective on the curriculum's role in organizing and delivering content. Therefore, options A, B, and D are incorrect as they are not associated with this specific definition.
