Explanation

The Planetesimal Hypothesis (Chamberlin and Moulton, 1905) proposes that planets formed from small solid bodies called planetesimals, which were created from material pulled from the sun by a passing star. This is a theory about Earth's origin. The other options: Thermal-convection relates to mantle dynamics, Tetrahedral is about Earth's shape, and Drift relates to continental movement, not origin.
