Final answer:
The correct answer to the velocity of lithospheric plate movement along plate boundaries is between 1 and 20 centimeters per year.
Step-by-step explanation:
Lithospheric plates, or tectonic plates, are large segments of the Earth's crust that move at varying velocities along plate boundaries. The movement of these plates is quantified in different measurements, often compared to the growth rate of hair or fingernails for a visual reference.
The typical velocity at which these plates move is between 1 and 15 centimeters per year. Therefore, the correct answer to the question about how fast lithospheric plates move relative to others along plate boundaries is (c) 1 and 20 centimeters per year.
