What geological process generates the world's longest undersea mountain chain called the Mid-Atlantic Ridge?

folding and breaking of undersea layers until they form ridges or mountains

subduction of pulled plate boundaries beneath neighboring plates

divergent plates spreading apart and magma pushing up and creating undersea mountains

deep areas of bedrock breaking into faults leaving steep vertical displacements

Mid-Atlantic ridge also known as the mid-oceanic ridge and is present at the floor of the Atlantic ocean and is a part of the largest mountain chain in the world.

The mid-Atlantic ridge separates North American Plate and the European plate. The ridge has an elevation of 7,713 meters.

The mid-Atlantic ridge represents the divergent boundary where the magma pushes up and creates undersea mountains.

Hence the option C is correct.
