How to move the player from one scene to another?

Question

Unity

I want to transfer the player object from one scene to another, in a unit. At the same time, save all its parameters, parameters of scripts that hang on the player, objects attached to the player, etc. How can this be done conveniently?
Now I'm transferring through the prefab, to which I load all the attached objects and data on the new scene.

A) Be able to serialize player states. Conditionally turn everything into json, and load it on the new stage, getting a new character indistinguishable from the old one. (technologically)
B) Load a new scene in addition to the old one. Transfer "physically" the player's gameobject to the new scene, and then delete the old one. (simply)
