Answer:
Option (C)
Step-by-step explanation:
In a divergent plate motion, when two plates moves in the opposite direction, the sea floor spreading takes place. As a result of which the lithosphere is stretched and becomes thin. The magma eventually rises up forming a ridge which is known as the mid-oceanic ridge. for example, the Mid-Atlantic ridge.
The rocks that are formed along this mid-oceanic ridge are the youngest and the rocks that away from the id oceanic ridge are the oldest rocks.
Hence, the correct answer is option (C).
