The soft layer of rock in the Earth's mantle is called the asthenoshere. The asthenoshere is a solid but able to flow slowly.
No. The outer core and part of the mantle are liquid, but that's about it.

It's only soft and plastic in that it is not as hard as the brittle rock of the crust and uppermost mantle.
The plastic-like layer of the upper mantle is called the asthenosphere.
As the question uses the word mantle which is a compositional layer of the earth, then the answer is crust.

If there were such a thing it would not be soft, it would be liquid, and would be called magma. There really is no completely molten layer of Earth except for the outer core which is composed primarily of liquid iron along with some nickel and other trace elements.

No layer is truly made of liquid rock. The mantle is sometimes, inaccurately, said to be liquid rock when it is in fact solid, albeit relatively soft. The outer core is liquid, but it consists of liquid metal, not rock.
