The theory that best explains the present arrangement of continents, oceans, and landforms on Earth is **B) plate tectonic theory**.

Plate tectonic theory outlines how the Earth's lithosphere is divided into tectonic plates that move over the semi-fluid asthenosphere beneath them. This movement is responsible for the current arrangement of continents and oceans, as well as the formation of various landforms. While Alfred Wegener's continental drift theory (which is related to the idea of Pangaea and the continental puzzle) was an important precursor to plate tectonic theory, it is the latter that provides a more comprehensive understanding of geological processes and the dynamics of Earth's surface.
