Step 1: Understanding land forms.
Landforms are classified into primary and secondary landforms. Primary landforms are created by natural forces such as tectonic movements, while secondary landforms are shaped by weathering, erosion, and other factors.
Step 2: Second order land forms.
Second order landforms include features like mountains, plateaus, and plains, which are developed after the initial formation of the Earth's crust. Therefore, the correct answer is option (C).
