Answer:
B
Step-by-step explanation:
What is a divergent boundary:
In plate tectonics, a divergent boundary is a linear feature that exists between 2 tectonic plates moving away from each other.
They can produce rifts, which become rift valleys.
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that magma rises to fill.
Sedimentary rocks form due to deposition, and accumulation
Metamorphic rocks form in a transformation of existing rock to new rock in a process called metamorphism.
Igneous rocks form through the cooling and solidification of magma or lava.
When the filled gaps of magma cool off, it will produce igneous rocks.
