The oldest oceanic crust is found at the mid-ocean ridges. Thus, option "A" is correct.
<h3>How old is the youngest oceanic crust?</h3>
The ocean crust is about younger than 200 million years (for example, smaller than 5% of the age of the earth).
The crust is most naive (still being created by volcanic eruptions) along the axis of the mid-ocean ridges and increases in age down the sides of the mid-ocean rises and out onto the more serious basin floors.
Thus, option "A" is correct.
