ACombining two or more branches of code into a single code base

BCreating a copy of existing code, isolated from the original code

CReleasing a specific codebase into a production environment

DTagging or labeling a particular codebase as production ready

Branching means that you create a new version from the code that exists indepently from the original code. It is not isolated forever, it can be merged back later.

Question 2

Not being able to explain to management should never be the reason to not do it. It doesn't only provide some data to programmers, the problem is that code coverage alone is not meaning a lot.
