The correct option is A Only 1 and 3

Seafloor spreading hypothesis, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from them.
This idea played a pivotal role in the development of plate tectonics, a theory that revolutionized geologic thought during the last quarter of the 20th century.
Seafloor spreading occurs at divergent plate boundaries. Seafloor spreading is not consistent at all mid-ocean ridges. Slowly spreading ridges are the sites of tall, narrow underwater cliffs and mountains.
Rapidly spreading ridges have a much more gentle slopes.
Seafloor spreading disproves an early part of the theory of continental drift. Rather, Seafloor
spreading helps explain continental drift in the theory of plate tectonics
