How is a branch called "my-bug-fix" started to develop a fix needed in a product?

Question

Options

• Agit branch -b my-bug-fix
• Bgit checkout -b my-bug-fix
• Cgit checkout my-bug-fix
• Dgit branch my-bug-fix

• A
  3% (1)
• B
  94% (34)
• D
  3% (1)

Explanation

The correct Git command to simultaneously create a new branch and switch to it is git checkout -b my-bug-fix. The -b flag tells Git to create the branch if it does not already exist, then check it out. Choice A is wrong because git branch -b is not valid syntax (git branch does not use a -b flag). Choice C (git checkout my-bug-fix) would only switch to an existing branch; it fails if the branch does not yet exist. Choice D (git branch my-bug-fix) creates the branch but does NOT switch to it - you would still be on your current branch after running it.
