The correct option is:
**Oceanic crust is thinner and younger.**
To elaborate, continental crust is generally thicker and composed primarily of lighter rocks like granite, while oceanic crust is thinner, denser, and primarily composed of basalt. Oceanic crust is also younger than continental crust, as it is continuously being formed at mid-ocean ridges and is recycled back into the mantle at subduction zones.
