Answer:
Option (D)
Explanation:
In an oceanic-oceanic divergent type of plate boundary, where two plates move apart from each other, the hot uprising magma comes out to the ocean floor along the mid-oceanic ridge, where the new materials are added to the crust. Here the lava solidifies and forms basaltic rocks, which are fine-grained in nature. The rocks near and along this mid-oceanic ridge are the youngest and as the rocks move away from this ridge, their age simultaneously increases.
Thus, the basalt rocks are formed at the center of the mid-oceanic ridge.
Hence, the correct answer is option (D).
