• None of the above

Answer 1

At the depth of around 100-410 km, mantle is partially molten and is known as Asthenosphere.

Explanation:

The asthenosphere is a region of the Earth's mantle located between approximately 100 km and 410 km in depth. It is partially molten and behaves plastically, allowing tectonic plates to move over it. The asthenosphere plays a crucial role in the movement of the Earth's lithospheric plates.
