Answer 1

The answer is B.

The Mid-Atlantic Ridge is by far the world's longest mountain chain, stretching a distance of 40,000 km from Iceland to Antarctic waters.  It is a result of tectonic plates pulling apart, causing magma to spill out and harden into ridges.  The Azores and Bermuda are parts of the ridge that stick out of the water.
