Which of these statements is true about plate tectonics? Continental drift on the Earth is caused by circulating convection currents in the deep interior. Continental drift on Earth is caused by the slow precession of Earth's spin axis. Tidal forces from the Moon and Sun causes the slow drift of continental land masses. Two crustal plate boundaries can easily slide past each other because of the presence of seawater. The Mid‑Atlantic Ridge is an area of continuous seafloor erosion which creates powerful earthquakes along a subterranean mountain chain.

Explanation:

The Tectonic plates make up the earth's crust and the movement of these tectonic plates that make up the earth's crust is due to the movement of the Magma of the earths crust that flows/moves in the form of convectional currents.

The earths crust acts as the heat insulator which when heated up due to internal pressures releases hot Magma flowing in the form of convectional currents apart from the convectional currents causing the plate tectonics to move other factors like ridge push and slab pull can also cause the plates to move as well.

a and b because with the other three, they simplify to something else.
