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.

When tiny ice crystals in clouds stick together to form snowflakes, the result is snow. If enough crystals form a clump, they'll become heavy enough to fall to the ground. When temperatures are cold and moisture in the form of tiny ice crystals exists in the atmosphere, snow forms.
The answer is:
The F1 generation will have all cleft chin.
The P generation and F2<span> generation will have cleft chins and no-cleft chin.</span>
