Options

Agit checkout -b RELEASE BUGFIX
Bgit checkout -t BUGFIX RELEASE
Cgit checkout -b BUG FIX RELEASE
Dgit checkout -t RELEASE BUGFIX

Explanation

Common mistakes.

A. The arguments are in the wrong order; RELEASE is given as the new branch name and BUGFIX as the starting point, which is incorrect.
B. The -t (or --track) option is used to set up tracking for a remote branch, not to create a new local branch from another local branch.
D. Similar to B, -t is for tracking remote branches and the order of arguments is incorrect for creating a local branch from another.
