Answer: Option (3)
Explanation: The plate tectonic theory describes about the large scale motion of lithospheric plates, due to the convection current that are generated at the mantle.
This tectonic movement can be constructive, destructive or transform plate boundary. In case of constructive, the plates moves away from each other, thereby forms a new crust. Whereas in case of destructive, plates collides with one another and the denser one gets subducted, thereby damages and consumes the plate at great depth.
In case of transform plate boundary, two plates moves slide past each other, and neither construction nor destruction of plates takes place.
Thus, the correct answer is option (3).
