Question

How are mid-ocean ridges formed at divergent tectonic plates?

The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
The stretching lithosphere is pushed up as the plates move apart.

Answer 1

The stretching lithosphere is pushed up as the plates move apart.

Step-by-step explanation:

Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.

I know that mountains are formed by the converging of tectonic plates, but ocean ridges are NOT created like this.

Hope this helps :)
