Where is the variable name stored?

Question

C++ / C#

And hello again to all the fierce programmers on Habré, as always, I ask you not to throw rotten tomatoes, because I am just starting to study the topic. In general, I decided to use unity, I went to this for a long time, but that's not the point. This is my second question on unity, it’s written in the book, I’ll try to formulate it as accurately as possible, I’m too lazy to look, in general it says that the value of variable primitives is stored on the stack, and such as string on the heap. Everything seems to be logical and understandable, but where the variable name itself is stored is not written anywhere :(

Answer 1

1A) nowhere
1B) in the metadata
Depending on what you need this "name" for
