Whizlabs integrated GitHub repository with Azure Boards for their Azure DevOps web application project. One of their developers corrected a label problem and now wants to close an open Azure Boards item. 

What should be the developer`s branch commit statement?

Answer options:

A.git commit -m "Finished Fixing AB#1 label issue"
B.git commit -m "Finished `Correct misspelled label` issue"
C.git commit -m "Corrected label issue. Closed AB#1"
D.git commit -m "Finished label issue. Fixed AB#1"
E.git commit -m "Finished AB#1 `Correct misspelled label` issue"

Correct Answers:D 
When you have set up a connection between GitHub repository and Azure DevOps Boards, you can use a reference to the Azure Board issue(s) within the comments during code commit. 
Azure Board issue mention must be in the following form AB#{Item ID}, like AD#1 for the "Correct misspelled label" issue. 
To trigger an update of the Azure Board item status to "Done", the AB# mention should be preceded with one of the words: "fix", "fixes" or "fixed". These words can be anywhere in the comment statement, but before the AB# mentioned. 

Here are the examples of the commit messages- 

Then after a successful pull request to merge your branch into the master, GitHub will update Azure Board item status to "Done". 

All other options are incorrect.
