In Git, a branch is a fundamental concept that represents an independent line of development within a project.
Here's a more detailed explanation:
* Branch in Git:
* Option Cis correct because a branch in Git is essentially a separate, isolated copy of the project's codebase where you can make changes without affecting the main codebase. Branches allow developers to work on features, fixes, or experiments in parallel to the main project.
* Other Options:
* Option Ais incorrect because while a branch does point to a specific commit (which represents a snapshot of the project), the description lacks the emphasis on the isolated and parallel development aspect that is critical to the understanding of branches.
* Option Bis incorrect because a branch is not a physical copy stored on disk; it is a logical reference within the repository.
* Option Dis incorrect because that description better fits the concept of a fork, not a branch. A fork is a new repository that is a copy of another repository, usually used to contribute back to the original ("upstream") repository.
