Answer:

They regularly move because of the convection currents of magma.

Answer:

It is due to the convection of the lithosphere and asthenosphere, the movement of plates occurs relatively to each other at different rates from 2-15cm/year.

Explanation:

  • The earth’s rigid outer layer called the lithosphere is broken into twelve large pieces called plates, which lie on the top of a molten layer of rock called the asthenosphere.
  • These plates present in the planet’s surface tend to move due to extreme heat in the earth’s core that makes the molten rock in the mantle layer move in a pattern called a convection cell.  

Thus option A is correct.
